@Jacanuk: I took bio on school, and my girlfriend has a bio degree. Neither one of us remember being taught in any bio class that the definition of "natural" has anything to do with reproduction. Care to share your source?
You need to learn to read what i wrote, But since you claim to have a GF with a biology degree, you should know that for a species to survive it has to reproduce, and since that takes 2. It´s pretty obvious that its pretty natural for a species to mate with the opposite sex, its again pretty obvious that it's unnatural for a species to "mate" with its own gender.
And since you still haven´t with your waste knowledge of biology been able to link, prove or otherwise that animals have the same concept of sex and gender, its again not even once proven that homosexuality happens in nature, since its again and you with your biology knowledge should know this, not just about sex with the same gender, unless you also start to claim that it is what makes you gay.
Please provide your source showing us that definition of "natural."
There are countless acts that are not possible of resulting in reproduction. Is my mother and father's sexual relationship unnatural because she doesn't have ovaries?
"its again not even once proven that homosexuality happens in nature,"
And here you have your biggest problem.
You and Wikipedia have yet to prove that animals have the same understanding of sex and gender as humans and that the "homosexual" behaviour witnessed is actually that and not just basic instincts and a fluke because the animal either isent in contact with the opposite sex, like with the gay penguins in a zoo (People forgot in their gay thoughts that penguins in nature has a behaviour where males take care of the egg, and females gather food, and that the two male penguins just showed normal behaviour, not to mention that they usually stick to one mate for life) or a case of a male/female exerting its dominance over other males/females.
So again prove that and we can agree that homosexuality exists in nature, otherwise stop trying to prove something that you can't.
