Being straight is natural, being gay is not. At the very most it's a mental illness that one is predisposed to by genetics or something. Also, you are implying that all decisions are conscious ones. Being unconsciously influenced into making a decision is still making a decision. Subconsciously deciding something is likewise still a decision.

Maybe you're gay or bisexual and have to choose to be straight

or, maybe, you're a butthurt faggot with no valid argument. I know which I'd bet on. "Uhh, you don't like gays?? that must mean that you're a gay!!!!" is a hilariously low-IQ response that, unsurprisingly, is common among homosexuals and their supporters because they have no valid justification for their sodomy.

Disingenuously misrepresenting what I'm saying and following it up with a preschooler-tier insult doesn't paint the best picture of your intelligence.
