Violent and strict feminists are probably feminist if they seek equality. I don't think it's a good position to be in, but that's it
There is a popular trend of "all men", or "the world would be better without men", this is not feminism, and that's the definition of "extreme feminism" for me. Misandry is extreme feminism. These people can go fuck themselves. They're enemies of feminism.
Hating others is easy. There's a lot of xenophoby, homophoby, transphoby, sexism. We don't need more hate from the marginalized people themselves.
I hope what you're saying is not true. I've seen things that make me think it could be, but I still hope must people aren't morons.
