I feel like this is really unfair.
Robert Putnam has chronicled how third spaces are gone (more than 20 years ago). This is a major problem in society and it doesn't just have to do with males and it does not only have to do with incel oriented stuff. "Deaths of despair" are up.
When you sit down and write this stuff I think you need to stake a step back and ask what you are contributing. This is just a mean screed aimed at men and doesn't offer any evidence for why you think lonely men should be cast as just wanting undeserved attention from women.
I know personally that I'm lonely. I have some working relationships, I communicate with my family and friends sometimes, but that's it. I don't want attention from women, that does not matter to me. It is exceedingly easy to get caught up in what is basically anti-social activity (browsing the web, posting on Hcker News - seriously), then you hit your 30s and 40s and you realize you haven't formed any real relationships with people in awhile. It can hit like a load of bricks and then where do you go? I don't know what up with the younger crowd but they obviously feel like they don't have a place anymore.
I just think what you said is not kind at all and tries to turn what is a real problem into some online talking point. This isn't about a bunch of boys caught up in incel rhetoric (you sound like you are caught up in some rhetoric yourself), but it is real people suffering with society being entirely different than it was in any other generation in history.
