I agree with him that you shouldn't assume people are gay then use it as an attack without knowing for sure. Heck, you shouldn't attack at all, especially your own family.
Though I understand too. My parents told me straight up they're gonna disown me and that I'm going to hell if I keep up my religion. -_-
And no they don't know. I may be scitzophrenic but they shouldn't judge. To those trolls, I'm now the "schitzophrenic anarchist libertarian satanist furry" who doesn't know what she's talking about cause she's crazy. I admit my views are pretty out there, but at least they could ignore me instead of attack me, or at least attack with maturity instead of in a way to hurt me.
