"That’s so gay"
i had a coworker who would say “that’s gay”. When I would look at him sideways, he would just say, “Oh, come on! I don’t mean it like THAT! Look, I HAVE gay friends.”
There is no way to replace a negative adjective with “gay” or “queer” and not “mean it like THAT”. If you are queer or an ally or a decent human being, you will NEVER be okay with that and you will ALWAYS try to educate those people who think it’s acceptable.
