Stop theorizing on real people's sexualities. It's not our business. And saying a straight guy that shakes his ass HAS to be queer is doing nothing but continuing stereotypes. He can post what he wants, and if you don't like what he posts, then don't look at it, otherwise you're just putting yourself into an upsetting situation.
Also, if someone came into my dms accusing me of queerbaiting, I'd block them too. Someone that deep into their own theories obviously wouldn't listen to me if I explain myself.
