Is being gay another mistake in nature?

_Enigma_
Quick disclaimer: I don't care if I hurt anyone's feelings, I am looking at this objectively. and if you get offended by something you chose to read, you have issues you need to work out. I don't think there is anything wrong with being gay in a morale sense, I am looking at this objectively.

Life is complex, and generally the more complex a thing is, the more likely it is that something will go wrong. We see this with people that are born with missing or deformed limbs, people who are born retarded, etc. These are clearly not intentional, as they only make survival harder rather than easier, and the same can be said about being gay.

There is no advantage to being gay. You cannot reproduce with the same sex, which would only lead to extinction if a large majority of a species decided to be gay suddenly as they would not be reproducing. There is no benefit to being gay that I can see, but maybe I'm just not looking hard enough.

So if there is no advantage to being gay and it's only a detriment to survival, then could it simply be a mistake due to how complex life is, especially given that there are plenty of mistakes in nature, so it's not as if I'm suggesting something wild?

@InfoBot I would like to see what your opinion on this is.

Yikes, didn't think I was going to survive GAG moderation! We got through though. That was a close one.
