I don't think there's anything wrong with homosexuality. Our sexual orientation isn't something we choose. I didn't choose to be straight. I don't remember thinking to myself one day "Hey I'm going to be straight!". I'm sure gay people didn't just say "Hey, I think I'll be gay!". Why anyone would think that sexuality is a choice is beyond me. I'm sure some sort of biological, genetic or environmental factors come into play, but how can we possibly control these factors? You cannot choose your sexuality.
Of course you choose it! If I just broke down right this second and made out with a guy after I've lived a life with no signs whatsoever of homosexuality, would you still say that it was biological? People who say that it's not a choice are just the people who don't want to take responsibility for making that decision.
It's true that heterosexual partners are required to continue the human race, but that doesn't explain why homosexual behavior occurs in other animal species, which has been well documented. I'm fairly certain that other animals don't choose to be gay or straight, and while one may argue that they don't have the brain capacity to choose, it doesn't take away from the fact that we're all essentially animals on this earth. It's a perfectly natural occurence.
So we should just allow ourselves to be lowered to the same level as animals?
And they also need to stop bringing religion into the argument. Quite frankly, it has nothing to do with it.
I think everyone else needs to stop pushing religion out of the argument. It has everything to do with it.
