No one chooses to be gay.
Yes, indeed, all of us “choose” our sexual behaviors, but none of us choose our sex.
Granted, there are folks who are born with upset chromosomes, but rarely, and then there are those with enhanced or exaggerated residual/duplicate organs, again, very rare, but still, sexuality ( the actions relating to sex) are indeed choices. No one acts sexually just because.
In fact, all of us, even those with genetic aberrations of the body, are fearfully and wonderfully made! God says so!
