ELI5: Why so many people on the internet hate on Feminism and Feminists.
gpt
Many reasons:

Some people feel that feminism has made its impact already and the people who still consider themselves feminists are just being whiny (the law no-longer discriminates and women are free to subvert gender expectations; in most western countries at lest).

Some people recognise that there is a lot of discrimination against men (at least as much as there is against women), and think fighting against just one side of sexism is inherently sexist.

Some people are massive dicks and just want to vent at someone.

Some people are very misogynistic and don't want women to try and think for themselves.

Some feminists are extremely sexist and quite frankly deserve all the hate they get (there are many '"feminazis" who think that women are not only equal, but much better than men, and hold extremely insulting and idiotic views based on that).

Some people get the perfectly nice feminists confused with the "feminazis" and hate on them for stuff they didn't do/think.
