I think that it is in some way a genetic defect. In no way is homosexuality a benefit to any species scientifically. Why would we evolve or adapt to no longer reproduce? I would say it occurs naturally, but it is not a good thing.

If homosexuality didn't have any kind of evolutionary benefit it would have died out millenia ago. No one knows exactly why it evolved, but there are a few possibilities:
- Population restriction so that ressources aren't depleted as fast, which has to go hand in hand with...
- Caring for (formerly mostly related) children which lost their parents (since they still contain a certain amount of genes of oneself it is better than having no children). Today that goes for any child of course and could help society.
- And possibly others which we don't even know about.
It's good that at least you agree that's naural. Since you agreed to that, the worst thing you could say would be that homosexuality is a genetic illness, but even that wouldn't allow you to cut down on the civil rights of homosexuals.
In any case, we are long past the constraints of Nature. We take into account the fact that homosexuality is a result of genetics and not a choice, and that is all.
We strive not to discriminate on other genetic aspects (skin colour, eye colour, height, sex...) so why should we discriminate on that particular aspect? Because it is icky? Grow up.
There are two distinct benefits to society with homosexuality. Firstly, it's a safety valve against over population. Secondly, it's extra caregivers if something happens to the biological parents.
The more sons a woman have, the higher the chance is of the new one being gay.
Your question would only be valid if we all were becoming gay. As long as it's only about 5-10 percent of the population, it's clearly an addition, not a replacement.
Besides; what does it matter whether it's a genetic defect or not? Downs syndrome is a genetic variation (or defect), but people with it still has just as much right not to be discriminated against as anyone else.
Breathing oxygen was a genetic defect when it came, and when oxygen became abundant in the atmosphere, it killed off almost all animals on the planet. It wasn't a good thing then, but it is a good thing now, don't you think?
Genetic population control immediately springs to mind. Plus non-competing males could be a boon to the hetero males of a social species since they could be kept around to help protect the group and forage for food without threatening any of the hetero males' breeding rights. Your inability to think past your foregone conclusion long enough to even dream up a hypothetical is proof of nothing save your own mental deficiency, and your belief that something has to be positive to be natural is proof that you don't know what the fuck you're talking about in the first place.
I would say it occurs naturally, but it is not a good thing
Well, it does occur in nature. Therefore it must be a good thing.
LGBT people come from hetero sexual couples after all. And this may come as a shock to you, but some of the hetero parents of these LGBT children support their right to be who they are.
Straight people are involved in Pride marches. That rainbow flag they'll most probably carry? It means Diversity . So deal with it.
Where do people get the idea that any species is "perfectly evolved"? Or finished with the process of evolving? Even if you consider homosexuality to be a "mistake', so what; birth defects of various types are a part of nature, but you've chosen to hate only that particular variant. Your compassion is underwhelming. Do you similarly hate a child born blind or deaf?
The prevalence of contraceptives is proof that not everyone wants the same things. That's nature...
"Why would we evolve or adapt to no longer reproduce?"
Allow me to direct your attention to, say, ants. Species in which 99+% of population is sterile. And yet they are one of the greatest successes of evolution.
Confused?
