As many have noticed, several anti-loli dipshits who cater to the anti-regressive movement, like the gab founder, have expressed remarks such as "satanic garbage" in regards to mere offensive pornographic artwork, and has also attempted to ban porn but relented due to a larger outcry.
I suspect that these individuals are tradcons, and are attempting to take over the opposition of the regressive left to further their personal agenda, which will only damage it by fracturing the dissident right and driving off the libertarian left.
I also suspect that 8chan owner Jim banned lolicon from his site because he personally hates it, and simply asked his lawyer to dig something up to use as an excuse, which fratured the community and put any user who decided to use Mark Mann's 8chan.moe at risk of abuse by the owner, who has a history of being a goddamn lolcow who got his nudes leaked and is accused of violating sex offender laws.
On the subject of Mark Mann, he defends unteralterbach despite the fact it depicts real minors, showed it to his underage niece and got disowned by his aunt for it, and is accused of running CP discord servers.
You don't have to be Tradcon, SJW or anything other that a fully-functioning, fucking adult to think that people who care about Loli-porn suffer from stunted emotional growth and a crippling lack of self-confidence. I don't blame them for that, everyone goes through phases; I do blame them for choosing to address their insecurities in fixating on sexualized imagery of underage children rather than getting their fucking act together and making an effort to play the part of grown-ass man.
If you're worried about people 'kink-shaming' you there are plenty of subs on reddit to gain sympathy.
God forbid someone understand how precedence and loopholes work. This is the "soft sell" and "foot in the door" strategy at work, getting people to agree to destroy something nobody would defend so that they can sneak in the stuff we should be defending using the same laws and movements.
We can mock why someone would be into such a thing, but allowing it to be banned or sacrificed on the altar of "well, I don't wanna look wierd!" will only leave us defenseless when they come for everything else.
Get the hell out of here with the Slippery Slope nonsense. There's a wide sea, sprawling desert and endless plains between hand-drawn CP and any other medium that risks censorship.
I believe in freedom of speech but anyone saying "Ya'll need to go out and bash some gay people" needs to get done for instigation.
In the same way I believe in artistic expression but not when its done specifically to stimulate and promote tolerance for what are one of the few truly deviant desires. Necrophilia? They're dead, fucked up but no inherent harm. Sadism? If its a willing partner, whatever floats your boat.
This loli-shit? Fetishising vulnerable children as sexual objects and making it seems as though its something that can be tolerated as being 'normal' rather than a pervasive fucking danger than encourages people with serious emotional and psychological issues to indulge rather than suppress their latent desires?
Some people, quite a lot actually, will say "the only good pedo is a dead pedo". I'm not one of them. I actually realise that many of them can't help it. They either have scrambled neurological pathways that fucked up their attraction stimuli at an early age or they're emotionally incapable of dealing with mature adult women and so seek immature juniors they can have confidence with. Being that way is not their fault. Failing to realise/care that those desires are a threat to children is something you can 100% blame them for and indulging their fantasies through loli-bullshit is an utter failure to rein in those tendencies.
So no. People opposing the distribution of this kind of nonsense is not the first step to them taking down Michaelangelo's David for flashing his junk.
Except, we already have seen the consequences of this slippery slope in actual reality. Australia already started the trend of banning adult women from porn for not having boobs big enough, for all the same reasons you listed. Regular manga gets confiscated when being imported despite being nothing but moe bullshit.
The current American law already states that a random person gets to decide entirely on their own judgment if its considered obscenity or not, and therefore illegal.
I won't pretend its some high art that deserves respect or even normalization, but any law or rule you would make against it would be used in far more ways and ways that are equally guilty under any umbrella made. "Simulates perverse fucking danger as normal"? Shit ban all rape porn, and blackmail, and snuff. Even if its completely fake, that applies back to the lolishit too. And once that's gone, oop now all edgy media is guilty and on the chopping block too.
Its literally the most disgusting shit, that's why its the easy sell to get people to throw down their arms and let it be banned. "Slippery slope nonsense?" As if we didn't in less than a decade go from "let gays be married" to "suck the dick and drug/mutilate your children."
That's the first good comment I've seen on the other side of this thread because it actually made me sit down and reassess my entire position (not because I thought I was wrong, but to make a sincere effort to reevaluate whether I was being reasonable rather than emotional). My first reaction was, predictably, "fuck yeah, ban it too" but to extrapolate from that, should we ban , media that includes rape scenes, murder, etc. No, of course not. So what's the difference? It's a question of degree. One is very clearly fictional, the other is (frequently) deliberately designed to convince the viewer it is real, to the extent that people watching it might often think, "Shit, do I need to call the FBI?" But what if it has disclaimers, the actors appear to say they're fine, etc. No. If its entire purpose is to stimulate unhealthy desires (unless you want to say that sexual stimulation from the idea of rape and murder are healthy? And don't say "women fanatize about rape. female fantasy and realistic rape are v. v. different things) it is not something that is in the interests of the vast majority of society.
"But we need to protect the interests of minority groups, we can't deprive them of their needs just because they don't match the majorities". There are certain groups who don't get to indulge their natural instincts because the welfare of the group supercedes them (psychopaths) or because the safety of a different vulnerable group (children) is a higher priority. Determining where that line were something crosses from edgy, to actually dangerous, is always going to be a judgement call but all rights have similar boundaries based upon our ability to make rational judgements.
You shot yourself in the foot with the last comment. "Gay marriage was the mistake that led to SJW insanity." Allowing gay marriage was perfectly fine (though I personally think it is was unnecessary) the fault in society lay in its/our failure to apply the breaks. Every minority group that is conceded some measure of power eventually uses it to reach beyond what they deserve, it's an established pattern. That doesn't in any way delegitimize their initial problems or concerns. The problem is shifting from one extreme control group (ban everything, no liberalization) to a different extreme control group (let do what thou wilt be the whole of the law). Our issue as a society is letting the extremists hold control and promoting the slippery slope argument is just arguing for one form of extremism over another.
Finally, not that the slippery slope isn't fallacious (it is) but if you want to employ it the closer fit is Japan were decades of indulgence of this shit has led to the growth of the j/k sex industry, trains that need women only carriages because of the chikan that frequently specifically target school girls, and the chaku ero and junior idol sub industries that lead to crap like this https://twitter.com/kabukicho01/status/1235452171832811522
Once again, the slippery slop is bullshit. Its always possible to apply the breaks if you fight for the right things and rejecting Z doesn't mean you need to reject A. This is a specific example of where that culture goes when allowed to develop without reins. I'm saying this is the specific point where intervention is warranted. Not banning all art and comics, not letting anything go. This point - sexually explicit loli art - is the reasonable tipping point.
