All of my gay friends involuntarily are gay/bi
I don't think it would be logical for, say, someone who stands to lose a lot by being gay to choose that. Why would you choose to be gay in, like, Saudi Arabia or Nigeria? Why would you choose to be gay with super religious parents? When LGBT teens are 40% of the homeless youth population? When you expose yourself to be shunned by homophobic friends and family? There's no benefit to homoloveuality over heteroloveuality.
