I think your focus on individuals, rather than populations of species, is clouding your thinking. Evolution is understood as occurring within a species, not a single organism or pair of organisms. Moreover, evolution does not move in a specific direction. It produces scattered mutations, some of which prove to be beneficial in the immediate environment. It is a process driven by randomness. If you really want to think about this rigorously, read EO Wilson or SJ Gould. The homosexual population is tiny, most estimate it to be approximately 2% of the human population. Nobody arguing in good faith would assert that the size of the human homosexual population is significantly impacting our fertility rates or ability to propagate the species. Because homosexuality and non-reproductive mating occurs across species, and seems to be most frequently observed in mammals, specifically primates, evolutionary biologists who engage in the discussion (or at least those I have read) fall into two camps: They believe it either (i) is statistically insignificant "noise" or (ii) is the result of evolution that must serve some beneficial purpose in social species. Of course, others, discussed above, believe homosexuality is not transmitted through any direct genetic mechanism at all and is, instead, the result of intra-uterine hormone levels (which themselves may or may not be subject to genetic determination).
You've missed my point and continue to assert that this gay 'mutation' (your words) can somehow be beneficial for the species as a whole, in the way that a birds changing of feather colors could be. But your 'mutation' doesn't in any way make the population as a whole more likely to survive. It makes it less, because there are now that many less reproducing organisms.
And you've still yet to point out ANY species benefiting from non reproducing members...

Finally, if you want to disregard the Journal of Endocrinology as a propoganda rag that produces one-off studies, I can do nothing but conclude you're approaching this debate in bad faith and there really is no reason for us to engage in this conversation any further.
Firstly, I never referred to the journal (or even the study) as propoganda. Solely that this weeks breakthrough is next weeks rebuffed theory. There are countless, countless examples of this over the last 25 years, and if I wanted to dig a little I am sure I can find a more recent study than the one you posted declaring those findings invalid. And if you waited a few weeks/months you could find one reversing mine.
Secondly, unless the Journal of Endocrinology is unlike EVERY other medical/scientific journal I've ever reviewed, they don't have a 'staff' of researchers, but rather individually funded, individually undertaken studies that are published in the journal for peer review. Since you don't know that, I am led to believe you haven't spent much time in these journals, and your above posting is the result of (admittedly) impressive 'google-ing'

Just because people choose to do it that way does not mean that they are not able to do it the old fashioned way. I'm pretty sure if the only folks left on this rock were the gay ones and for some reason none of them had any scientific knowledge then they would figure out what to do.
Gay people are just as capable of reproducing as you are, and I'm guessing quite a bit more capable, they just choose different methods.
You lost me here... Why are they more capable? Feel free to cite facts (or even well reasoned opinions).
And I never said not able. I said wouldn't. If the last few people on earth were bi-sexual than by all means you're right. No problems.
But to assume that a gay man, having NO desire to procreate with a a female, could 'perform' (word used in an effort to keep it family friendly) is quite an assumption. I certainly couldn't 'perform' with a man. So why is it they could?
