One of the key third-wave critiques is that second-wave feminism was only ever really about middle-class white women. Obviously, an actual third-wave feminist wouldn't have concluded that feminism is about white privilege; they'd have said we need to change the direction of feminism to make it more inclusive of "diverse perspectives" or some such.

I was joking when I implied they were trolling feminism, but if a group of saboteurs had gone undercover to make the movement irrelevant, I don't think they could have done any better.
