Well, on that issue, he's not really wrong.

There's a metric fuckton of feminists who genuinely feel like the world is better without men, and are emasculating or feminizing boys because they are asserting that femininity is normal, and masculinity is a disease, or innately toxic. They don't raise boys as boys, they see boys as malfunctioning girls, which does irreversible damage.

Then they teach the bigotry, misandry, and sexism to girls. I can't tell you how often I heard "You have no idea how hard it is being a girl" by upper-middle class white girls growing up.

They're not trying to genocide boys. They'd just prefer men go extinct, and they think feminizing boys is good for them, even though it's destructive or even lethal.
