What do you say to a women that calls herself " antifeminists?"

I have alot of gals in my school that not only secretly talk shit about anyone that' has anything to do with feminism but also loudly call themselves " anti feminists"

I don't get it why would they ever want that ? Its kinda like a black person going around telling people that racism is good

I'm not usually the one that starts debates but they constantly try to " expose" my feminism values by trying to prove that feminism is fake and it's getting annoying and exhausting
