a person who goes around calling people girl has likely at some point, consciously made it part of their language. they don't use it at random. it's like saying "can i trust you?" on some level. can i trust you to not be embarrassed by femininity? can i trust you to not flip out at the implication of being perceived as girly? are you ok with being girly, even if society perceives it as wrong for you to be girly? do you understand these things as valuable, as fine, as normal, as neutral, the same way masculine terms and assumptions are? do you not view this as a type of humiliation, with the implication that being treated as feminine is degrading? a person who goes around calling people dude or man or guy or bro has never fucking thought about it ever, and if asked to stop is suddenly from california where it's ok to do this and why should i even apologize for doing this you're being hysterical really
