Nonsense I was referring to what the scientific community think is obvious, not what you think I think is obvious.
Please, cite your sources. As far as I am aware, the scientific community does not think homosexuality is 'obviously wrong'. They believe, and the evidence shows, homosexuality has a societal role to play, and the human species has evolved as such.
A man is a male because he has a male reproductive organ. A woman is a female by nature of having a female reproductive organs. That’s basic biology. When a baby is born one can tell by biology whether it is male, a boy, or female, girl.
What about hermaphrodites? People with female genitalia but XY sex chromosomes? Sex is anything but simple.
They can’t tell what sexual attractions the baby has nor can they define it by them, so that’s not basic biology.
Then you have a warped view of biology. 'Basic' biology are things like the cardiopulmonary system, or the nature of DNA, or how enzymes work. You can't tell that just by looking at someone. I think you're conflating biology with extremely rudimentary medicine.
which is a contradiction in terms, how could something evolve that couldn’t reproduce itself. Same-sex cant reproduce.
Simple: kin selection. Though homosexuals themselves can't naturally reproduce, they do help their kin to reproduce. Since their kin have essentially the same genes that they do (compared to their kith), it is advantageous to 'boost' the reproductive chances of said kin. It is simply a question of finding the best proportion of homosexuals to heterosexuals (in humans, we've evolved a 1:19 ratio).
Moreover, homosexual couples act as a sort of natural adoption agency: orphans that would otherwise die in the wild can be taken in by homosexual couples, since they are guaranteed to not have kids of their own.
Yes extinction. It sounds like a disease if the male and female of the species increasingly don’t want to couple to reproduce.
Nonsense. First, heterosexual couples use vast amounts of contraceptives and birth controls. Second, people don't 'choose' to be gay; I, a fully-fledged homosexual, can't wait to become a dad.
You know 'endemic' has meanings outside of pathology, right?
