it was an ideology based movement that used arguments (generally enlightenment ideas based on personal freedom, the right to choose, self determination, Suffrage) and decided to change the culture of its time at it's inception, through political outreach and participation. with one glaring flaw, it didn't have much respect for human agency and eventually made mistakes along the way (prohibition, sparked by feminism's religious/christian roots) due to authoritarian sympathies. it was a massive success and then the shit hit the fan in the 60's into the 70's when post modernism managed to creep it's way into the left's zeitgeist. at that point, you had feminists saying that there were cultures in the amazon and the jungles of africa where women were the heads of their populations and the patriarchy was inherently colonial, oppressive and capitalistic. this is where the lines got blurred and kickstarted the third wave's failed social experiments. (men and women are only different due to culture, not nature. evolution ends at the neck, boys and girls can be raised to believe they are the opposite gender with no potential problems occuring.) like how the hippies tried to create a classless, genderless, utopia. there were pol-scientists and psychologists/therapists who even went so far as to give the experiments a go. some were so bad that they literally forced some out of the movement, for example, after a child had a botched circumcision, a therapist of the boy decided his parents should just raise him as a girl, because the prevailing wisdom in his Po-Mo circles argued gender was a social construct. that kid wound up killing himself. when you start peeling back the onion, the modern social justice movement seems like a natural evolution of this stuff, and they have co-opted alot of the Feminist movement, using marxist terms of oppressor and oppressed to describe interactions, and creating Micro-agressions and macro-agressions which play a bigger part in intersectional feminism. the movement has mutated, if you are a university student, this should be pretty obvious though.
