I think Tritemale had a lot of worthwhile points, too.
It's not useful to totally mash together young disenfranchised men with incels. Or if you want to, you need to justify it.
It's also very significant that the attitudes of the young men to feminism are pretty similar to the attitudes of young women. What this says to me is that in some way, it's not speaking to them and even repelling them. And saying t's just because young women want men to like them is not only dismissive, it gets right back to the tactic of feminists only listening to the voices of women who say things they want to hear - the rest are handmaidens. It's self-serving in an immediate sense but it hasn't done anything for feminism in the bigger picture.
At a more basic level, some of the problem for these young men comes, as a pp said, right out of inequalities.
One of the biggest problems with identity politics is that when you have individuals who have are on the bottom of the pile, not much money, not many prospects, ad they are being told they are oppressing others because they belong to a particular race, or sex, or whatever, the outcomes of that are not good. When they know lots of other people in the same boat, so they are not individuals but a group, it gets worse.
Because from that perspective it looks very much like you yourself are being systematically oppressed, and one of the justifications for that is your race and sex and maybe even sexuality. The helps being offered to others, scholarships, classes, focus groups, etc, for minority students or women, aren't available to you. The mechanisms supposed to be helping those others begin to look like something of a conspiracy to keep you down.
It's like a textbook lesson on how to create a radicalised group. The fact that there is a much larger group who just feel some unease about it all should be no surprise.
