As someone who's taken two college level psychology classes (and has asked the professors about this sort of thing), this is not true. The only thing mentally ill get is the fact that you're this delusional. I also see from the other comments that you believe God didn't design humans to be gay and stuff, but it doesn't have to do with God's design; rather, it has to do with the person's experiences in life and their personality, that of which God doesn't truly have control over because he gave humans free will. He doesn't want people harassing others over being who they are. He said to "love thy neighbor". No exceptions, no ands, buts, or ifs. Just to love them. So instead of treating queers like shit, treat them with respect and they'll respect you back.
