That's a pretty loose interpretation of Darwinism, but even Darwin would likely acknowledge that homosexuality is part of nature since there is overwhelming evidence throughout human existence (and non-human existence, seeing as it's been identified in hundreds of species). Maybe take some time to read about "overdominance" in evolutionary theory.Wait, you're all into Darwinism, right?
SCIENCE!
Please elaborate on how being born gay contributes to the survival of the species.
There are tens of millions of gay people in the world today, but it's not natural? Explain that.
Were all those people just "brainwashed"?
Only argument I've seen so far is "Men have stick, women have hole", and "God said so".
And why would anyone choose to be gay?
