It goes both ways I think too. Guys wouldn’t obsess over the idea that a single compliment might be flirting if they were more used to compliments in general from both sexes. On the other hand some guys are so afraid of misreading a compliment or normal friendliness that they can’t tell when someone actually is flirting. I sort of think there need to be more voices out there meant to speak directly to men and masc people about social literacy that aren’t trying to turn them into hateful, violent, incel republicans.
