I gotta say, I have to agree with Superdude up there. If you can Qin are going to keep repeating this you’d better damn well be willing to back it up. Otherwise, stop with the gaybashing.

And gaybashing is exactly what you two are doing. So stop it. Warning issued for hate speech.

This seems like odd reasoning to me. If it is gay-bashing, then why would it be OK to back it up? What makes it gay-bashing only if it is unsubstantiated?
