Justin Bieber,, yeah another question about bieber. I'm not a hater but why is the insult always 'he's gay'?

Seriously, who cares? Does it make him less talented? No. Does it make
him more talented? Obviously not. Why can't we all just agree that he
isn't very good without calling him gay? It makes no sense. And No,
I'm not gay. but if I was I don't see what the big deal is about it.
