We're all used to the obvious rot and see it every day; Advil's Black Pain Equity campaign, pronoun sections on corporate meeting software, "safe injection sites" funded by municipal governments being a hot bed for drug abuse. That stuff is so brazen that anybody with a brain and without an agenda will be repelled immediately.
But what about the subtle rot? I'll use the Onion as an example. Perhaps its a bad example since they are a good showing of obvious rot, but I just learned that they purged their old African-American neighborhood terrorized by ask murderer headline and it happened with no fanfare at all. A slow purging of old material deemed ungood; a memory holing except for the fact that the Onion used to be printed on paper and people just took pictures of the old headline. But the point stands -- I had no idea it was purged until I deliberately went looking for it, and its the only old "edgy" Onion headline that appears to have been purged in this fashion.
What else have others observed?
Literally horseshoe theory "right wing is just left wing but different color" stupidity, straight out of public school propaganda farms. Absolutely wrong.
You can objectively classify political ideology by one scale - control. The extreme right is anarchist. Extreme left is authoritarian. No right wing movement has ever been authoritarian and no authoritarian movement has ever been right wing.
I mean, that is how you want to classify things, sure. To me there's an extreme difference between a National Socialist and a Marxism though even if you might consider them equivalent given your scale. I also think there's a huge difference between liberaltarians that are racist and sexist compared to libertarians that are egalitarian.
"National" socialists are little different from the rest of the leftists. "To me" nah. Objectively. Political scales are not a matter of opinion where any fool can call anything left or right based on their personal relative values. That is yet again leftist word twisting dogma at work.
For any reasonable discourse there must be objective measurements and consistent definitions.
Nationalism does not swing authoritarian leftists right wing. The chicoms are, and soviets were, also nationalist. The german nazis were a hard left authoritarian government. Strong centralized government power and collectivist ideologies are left wing. Nationalism is not an element tied to either wing, it is a relative cultural element that is used to strengthen a nation of any type by intelligent leaders.
You have been fed propaganda your entire life, and fed yet more to be convinced that to reject leftism you should adopt another leftist ideology - that is the goal of the propaganda campaign aimed at convincing people the krauts were right wing. That is objectively false, and it is done to deliberately muddy the waters and allow leftists to pretend that the atrocities of the 20th century weren't directly caused by their ideologies, and to create the false perception that both wings are similar - to make it seem that both can be evil on the same scale. That is why the false "horseshoe theory" doctrine is pushed, to claim extreme right somehow wraps around from people that hate government to a leftist authoritarian collectivist ideology.
It's bullshit. You've been lied to, and when you tried to rebel against the left you were duped by another of their tricks.
