Perhaps there's a constructive version of this because I agree with the sentiment but it's a little harsh - dude is obviously feeling very betrayed and left out of society and either falling down the incel tunnel or doing recruiting for it.
There's some fallacies here like "anyone not acting in stereotypical Protestant gender roles must therefore be recklessly promiscuous" and that if some people don't want to have kids with some women then therefore -nobody- will do it.
Good luck out there everybody - the world changes in fascinating ways and it can definitely run some folks over but try not to get jaded and fall down a despair spiral.
They’re not completely wrong though. Data does show clearly that online dating has extremely lopsided behaviors. Women really do tend to message the top cohort of men by attractiveness much more so. Men have a more expected distribution. I think that causes a lot of men to really resent dating and women because they struggle and put in enormous effort and get nothing back. Online dating is a very toxic modern invention.

That fallacy isn't in there. Also, I would like to point out that almost all women have had more then 0 sexual partners before wedding. Hence your statement would actually be kinda correct of you remove the "recklessly". And that's definitely another contributer to declining birth rates/families - because neither of them will feel remotely as committed to each other then they would've otherwise.
None of these are singular causes. They're all contributing to the whole situation. Which is precisely why I never made any such fallacy in my earlier comment.
