Feminism should be invalidated as feminism has no valid reason to exist. Feminism is a hateful religion that is a blight on our society.
Being against feminism doesn't mean that you're aGaiNsT eQuALiTy or insert another bullshit feminist meme. It means that you don't agree with the rampant sexism that is feminism, that you don't agree with things like the Duluth model or any of the other insanely sexist idea's that they spew like 'rape culture', 'mansplaining', 'the future is female' (yea check that one out, the gist is men should be reduced to be a maximum of 10% of the total population..), 'manspreading', demonstrating against a male mental health gathering, 'Kill All Men' or any of the other insane ramblings of these people.
That some tween, teen or idiot twenty-some calls themselves a feminist because they actually do believe in equality doesn't mean that they are actual feminist. They aren't the ones who help write and lobby for sexist laws, they aren't the ones who write 'feminist theory'. They aren't the ones who get to determine what feminism means. People often try to revert back to the textbook definition of feminism while ignoring what feminism does. That is exactly like saying that the Democratic Republic of North Korea is a democracy and not some backwards dictator's playground. Sure, they call themselves a 'democratic republic' but that doesn't make them one.
