i think there is such a phenomenon as mansplaining, however, i do not believe that is what alto was doing. he is a man and he was explaining that white feminism is actually a term called “white feminism,” which i, embarassingly, did not know, and so it was useful information to me.
however, i have definitely been on the other end of mansplaining and i can tell you it does exist. but it doesn’t mean “a man explaining something.” it’s more of a condescending “i know better than you, little girl, so just be quiet while i impart my wisdom to you and i’m not going to listen or respond rationally to anything you have to say, so i’ll just reply to anything further that you write with some smirky bs and blow you off.”
that’s my experience, anyway.
