Listen, I don't know who needs to hear this, but Misandry exists and you can be sexist against men, just like racism exists and you can be racists against white people. It doesn't matter what some fringe feminist theory book says to justify male-specific sexism, it exists and the people who engage in it are bad people. I don't care what you've been through, NOTHING gives you permission to be hateful and exclusionary to ANYONE.
