It's one thing to be "casually homophobic" on some "don't talk about it around me, keep it to yourself" shit.
It's whole other thing to make a hateful song specifically targeting gays. Not just using homophobic slurs or anti-gay one-liners in lyrics like many 90s rappers did, but going all the way in on some "we hate gays" shit. You'd have to be actively homophobic to make song like this one. Like, "let's go and beat this faggot's teeth in after we finish this beer" level homophobic.
