It really has very little to do with men "being owed sex" by women. Most men don't really believe they're owed sex by women, or anyone for that matter. The big issue is that society has placed such an emphasis on premarital sex and random hookups and casual sex that young men are beginning to feel like if they aren't having sex they are missing out on an integral part of life, which is not the case.
Sure, there are definitely men out there who truly believe that women are simply there to please them and be their slaves, but that is not the case for the vast majority of men, even so-called incels. They have simply been led to believe that sex is an amazing, huge part of life, that it is integral to a normal life and, while it is important to a healthy relationship, it's not necessary to live a normal life.
It also comes back, in a way, to the destruction of traditional masculinity. If they can convince millions of men that sex is the only thing that matters, that it is the most important part of a relationship and of life, then that's all they're going to care about. They're not going to focus on other things such as learning new skills or trade or bettering themselves in some other way.
Of course, the funny part of all this is that by convincing men that sex is the only thing that matters, they are completely reducing women to only being important in a sexual way. Although, I suppose that's part of the plan too. After all, we can't have women being motherly figures or caring individuals in a household or in life in general. We have to have them choose careers that debase them and destroy their mental well-being. It really is all connected I guess. The destruction of the family unit, the destruction of traditional masculinity, the destruction of traditional femininity, the sexualization of children... It really does circle back to the destruction of traditional values in a way that lets them swoop in and replace traditional morality with some sort of perverted new age "progressive" morality.
Anyway, that's my $0.02
Pretty much and now the only hope for it not to end in a bloody takeover that purges many supporting this and enforces traditional values by an iron first is probably sex robots and artificial wombs.
I'm semi joking, the problem is while men are screwed by this, women are way more screwed by this (ironically), a lot of men did derive their purpose in raising a family and being the protector, if that is denied to them by the current society, they can easily nope out, survive with very little requirements and exist for themselves.
Women on the other hand, can't. Being more social they require more interaction and attention. Living a more hermit or isolated life like men would kill a lot of women so it's why incels are attacked so vigorously, they are the biggest threat. You want to present hell to a lot of women, it's men walking away refusing to interact with them than on their knees desperately seeking their affection. If my joke actually did come into fruition, you'd have less incels as they'd raise kids with a robot but a lot of old bitter women.
The females would have an absolute breakdown if men somehow abandoned society.
Look at history, a females survival involves inserting herself into a males life and sphere of things to be concerned about, which is why we're always asking why can't women let us have (insert thing) and just leave us alone. They can't. It's a biological imperative. They must be on our minds at every moment.
That's why it's darkly funny, if men had access to essentially 2Bs that could use artificial wombs to reproduce, feminism, leftists would just fail overnight since men can re-adopt their original roles without the concerns or hassles.
You'll have women that can get a guy because they never adopted this destructive behaviour but on the whole you'd have the split society, those raising kids in a family unit (with a robot) and on the otherside, cities of cat ladies.....
