Or is it really part of evolution and within time everyone will be gay and have to reproduce through test tubes and eventually with evolution everyone will be born with both sexes.
First of all, homosexuality is so totally removed from evolution that it's not relevant. Also, for the record, gay people ARE totally capable of reproducing, so it has no effect on the "reproductive potential" of an individual, so the point is moot anyway.
Also, since evolution only deals with genetically passed-down traits, and at this point it appears that homosexuality is absolutely not a genetically transferred trait. So evolution isn't related to homosexuality in the lightest.
Third, evolution does not steer species toward test tube reproduction. That clearly cannot be a goal of evolution.
Ok so I was being a little sarcastic. You did say that "The problem is, when evolution refers to "survival of the fittest" it is talking about reproductive fitness" The only way for homosexuals to reproduce would be to be artificially insiminated, have heterosexual sex, or a surrogate mother. It appears to be that more and more people each day are gay or coming out and they all claim they were born that way. I do however don't believe in a "gay gene". I have heard some people say that homosexuality is part of us evolving.
First of all, is homosexuality a specifically human behavior? If it is a fundamentally biological behavior, there should be some other species which share it. And, in fact, there are close to 500 known species which are known to engage in homosexual behavior, including elephants, dolphins, sheep, bears, deer, rats, cats, dogs, cows, rabbits, kangaroos, squirrels, whales, bats, pigs, mice, goats, as well as just about every other primate. And that’s just the mammals! There are many more birds, fish, reptiles, and even insects which have also engaged in homosexual behavior.
You also need to remember that evolution is described as a change in allele frequency of a
Population over time. Individual organisms don’t “evolve” any more than a single pixel makes up a picture on your computer screen. What is necessary for evolution to take place is for there to be a group of individuals, a population, within which genes can change and flow.
This isn't as black and white as it sounds. It's a very complicated subject. Sure, individuals engage in homosexuality some of the time, or even a lot of the time, depending on the species. But not all of the time- they still find time to mate heterosexually. Sex seems to be a very fluid trait in many animals, pretty much any sexual configuration that can be performed within anatomical limits is done by some kind of animal.
You can also consider the social benefits of a population in which all members can share the close bonds of a sexual relationship, not just males and females. In bonobo chimpanzees, the female-dominated social network is composed of close bonds which are shown by frequent homosexual interactions between female members of the group. In fact, more than half of an adult female bonobo’s sexual interactions will be homosexual in nature. Clearly, in the case of bonobo chimpanzees, the bonds formed between females by homosexual relations are socially stabilizing. A stable society is much more likely to promote successful reproduction of young. Thus, homosexuality would be an evolutionarily beneficial behavior.
With regards to whether or not it's based on genetics is also a complicated subject. There was research done in Toronto a while back which showed that the more older male siblings a man has, the more likely he is to be a homosexual. The hypothesis is that the mothers becomes immunologically sensitized to the successive male fetuses within her, since they contain male proteins that she is not used to. It's a pretty complicated phenomenon. We could get into the research if you really want, but it may have to wait a little bit as I'm posting from a cell phone...
I do want to make it clear though. This is in no way a stance on the MORAL position in favor, or against homosexuality. To do so would be commiting a naturalistic fallacy. To say that because something is natural, it is either right or wrong is clearly illogical. The moral discussion of homosexuality is reserved for other, non-scientific settings.
In regards to Ivellious' comment, I would just like to point out I don't think there is a "goal" of evolution.
