most Feminism isn’t about woman supremacy over men, and if it is, it’s possible femdom fetish content. The most extreme schools of Radical Feminism advocate for female separation from men by forming their own societies called female-only communities but that’s it.
Feminism is however, about pursuing what benefits women because it comes from a time of gender inequality. That’s why feminists advocate for pro-woman policy like legal abortion, access to free birth control, more general legal protections, etc,. But you won’t see them advocating for womens’ right to be drafted.
As to why feminism doesn’t really discuss incels (or if it does, in an extremely negative light), there’s a few reasons:
1) The vast majority of active-feminists are female, and don’t really care about men. If asked about how their policy benefits men, Intersectional feminists (aka “Liberal Feminists”) tend to say that they are intersectional with other political philosophies like socialism or progressivism. Radical feminists on the other hand reject the notion that politics has ought to benefit men, or brush aside the criticism because they don’t want to think about it.
2) Females usually simply don’t understand inceldom, which is why the ideology they crafted doesn’t understand it. Women are so used to being able to get a date/sex that they don’t understand *not* being able to obtain intimacy. Therefore from there perspective, incels are just *choosing* to not date women, and it’s because of their blinding hatred of women and high standards which is preventing them from getting laid. So from feminism’s perspective incels are the woman-haters who want to subjugate them for sex because they don’t want to date women who would accept them. In reality incels are misogynistic *because* they can’t get laid.
As for why feminism ignored how men are getting poorer than women, it’s because feminism is out-of-date. It comes from a time in the West when women were way more poor than men and hasn’t kept up with the changing times. Feminism is still stuck on the disproven wage gap instead of looking at the material reality that women simply aren’t an oppressed group anymore and if anything are now the more well-off gender playing life on easy mode.
