Being straight is natural, whereas homosexuality is a choice. I’m not saying there’s anything wrong with being gay, but to portray it as natural is patently false.
Forget all that religion stuff, I’m talking purely from an evolutionary stance. All beings have evolved so that they may best propagate their species, while being gay flies in the face of that. It’s fine to choose to be gay, but as far as it being natural, millions of years of evolution say otherwise
