That’s a bit of an exaggeration, don’t you think? Homosexuality is the completely opposite of normal sexuality.

Even if you don’t realise it yourself, I think you’re starting to show your hand. You backed off from calling it a perversion, which was good, but you’re really clinging to the idea of “normal”, which in this case, is definately inching toward bigotry. We like to classify a lot of things as binary options, even though they really aren’t. Sexuality covers a wide spectrum with “pure” hetero- or homo- as only the most extreme ends of the curve. Historically, there wasn’t even the concept of straight or gay, even though people engaged in both types of relationships. By naming it, we tend to pretend there are no other options or descriptors. I think indie-girls in glasses rockin’ cat-and-girl haircuts, knee-high stockings and doc martens are totally hot, but there’s no name for that. There’s not really any way to say that any one type of sexual attraction is the opposite of another. If you look for exactly the same things in a woman that another woman does, do you really have opposite sexualities? How is hers not normal?

Would you grant that transexuality is a glitch?
[/QUOTE]
Only for the person experiencing it, because it involves a disconnect with how the person relates to him/herself. It has nothing to do with how they relate to anyone else.

I say it’s a glitch because it has no benefit and serves no purpose. If humans were intelligently designed, I see no reason why homosexuality would exist. That doesn’t mean it’s a bad thing. But, biologically, mentally, whatever, homosexuality deviates from how human sexuality is supposed to function. The fact that evolution has, for some reason, been unable to get rid of it is strange, but I don’t think that makes it normal.
How do I know how human sexuality is supposed to function? Because the whole (evolutionary) purpose of sexuality is reproduction. That is the purpose of the sexes, the genitalia, and all that. If we reproduced like amoebas, then sexuality would have no purpose. But we don’t, and so it does.

You seem to be suffering from some form of the naturalistic fallacy. “Is” doesn’t equal “should”. All evolution and science can tell you is what something did or currently does, and how it does it. It has no goal or purpose.
There are plenty of traits that are invisible to evolution because their existence or nonexistence doesn’t affect the survival of the organism. Really, if you ascribe to the “selfish gene” theory, it’s probably one of the best guarantees of success. Aside from that, what is “useful” now may not be in the future, and traits that had no utility before, may suddenly become advantageous in a new environment.
As for what humans would look like if we were intelligently designed, I would think we’d be solid body organisms that reproduced asexually, so I don’t see how that helps your argument.
But again, the fact that a penis delivers sperm to an egg through a vagina does not mean that is a “purpose”. It’s just one of the things it can do. We essentially “make” purpose by how we choose to use or experience something. In fact, most of evolution involves co-opting a structure or system that was originally used for something else. Considering the ratio of sex acts to actual births, I think it would be difficult to say that the purpose of sex is procreation. If anything it’s “getting our rocks off”.
So, yeah, homosexuality is perfectly natural.
