No one is born straight or gay. You don't have those kinds of feelings until you hit puberty. You're not attracted to anyone sexually either. Everyone is basically neutral. However, you ARE born with the predisposition of whatever your sexuality is. Straight, gay, lesbian, etc.
I find it hilarious when ppl use the "environment" theory. I grew up in a stable family, both parents were present quite a lot and equally, and another thing is that they are very homophobic and so is my extended family and home country (Iran). If you want to know if it's a choice, just ask a gay. Don't go jumping to conclusions just b/c you were raised to hate gays. Who would you rather believe, a straight homophobe or someone who is actually gay?
And another thing, when twats say it's a choice it makes you sound as if you're speaking from experience.
Have you magically turned gay and back to know? Are you reading the minds of gays to know what they choose and don't? You're (the homophobic assholes) not me, don't know me and have no idea what it's like. You're not in my shoes and most importantly you certainly don't have the ability to somehow tell me what I choose and don't. WHY would someone choose to be gay, especially in a world like this where you're frowned upon, sometimes imprisoned or killed in some places, and why would you risk the bullying and possibility of loosing your friends and family over it? Why go through with something that gives you such a hard time? I didn't want to feel unnatural, depressed, etc. If it was a choice I would be straight.
