I don’t think most people care. Granted, maybe it’s the dysphoria speaking, but I love it when someone calls me “girl” and I’m 30. None of the people I know care. If anything it feels more familiar to call someone a girl or a boy than a man or a woman. The latter two feel very “official”, while the former feel casual.

Also I’ve absolutely heard girls call a group of men, “boys”. Like, one of the white suburban mom stereotypes is to call her husband and his friends, “the boys”. Like, “hey honey, how was hanging out with the boys” or “oh, he’s off with the boys doing who knows what”.
