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
Addendum: in a way it feels like the book "Brave New World", where society has become based on hedonism and pleasure rather than a truly human experience.
I will say when I was reading that earlier this year I couldn't help but think how it was nothing but a guidebook for the leftist utopia. That it's what they want.
I will also say that's why they are all so unhappy. Their whole life is about baseless pleasure whether it be casual sex or social media likes. I've never been the most social person so it really took Covid clownery cutting me off from everything to realize that even for a quiet not-very social person like myself how much of the happy in my life was from human experience. The stuff that sticks with me as the fun points of my adult life are the personal experiences with friends, family, even random strangers. That's what I remember fondly, not the things I've seen or places I've been. Take that away like they did in 2020, and I'm an angry wreck screaming on the internet just like they are.
I think you hit the nail on the head there. It's kind of a cliche at this point but that saying about what we have not being important but who we spend our time with being important really nails it as well. We can see the whole world and visit places that are truly awe-inspiring, but does it really matter if we don't have anyone to share those memories with, be them a friend or a spouse or family member?
I think people have changed too. For years now I would do like one big solo trip, the type of thing I just couldn't get other people to go along with me on. I liked it, because even though I'm not the most outgoing person I'd end up meeting interesting people in unusual places, etc. It seems like that's all but gone and people shut up and hide now and everything is designed around keeping people apart. The height of my travel fun the last couple years has been things really unexotic like camping with friends 30mins from home or hanging out with my cousin on his birthday. That's not to say I haven't tried "sights", but the last such trip I got bored and came home early.
I really do think that there is a concerted effort to make you untrusting of your neighbors and your friends and your fellow man. This started with the push to label anyone who believes something slightly out there or off the wall as some insane conspiracy theorist who thinks that the world is run by a lizard people, when in reality they just think that the government lies to us about stuff. Now it's turned into constant news articles about how everyone's buying guns, so you'll think that your neighbor is some psycho who's going to shoot you at the drop of a hat. Covid really exacerbated the issue too, because now they can label every individual that you don't know as some breeding ground for germs that's going to kill you and your whole family simply by being near you and giving you some horrible sickness. That's why media latches on to things like monkeypox because they can use that to further the idea.
