If being gay is completely natural, how come they cannot reproduce?

Yes, and we have the biological capacity to get aroused. There is nothing in biology that dictates a "pure" and predetermined form of sexuality.

Yes there is. Nothing in nature is without a purpose. Like I said earlier, sexual arousal functions as the driving force for reproduction. And the physiological capability of a heterosexual couple to conceive a baby demonstrates the evolutionary predetermined form of sexuality.

Urges to kill your own species or even your offspring serve no evolutionary/reproductive purpose that we know of, either.

That is exactly why I referred to such occurrences as unnatural and not normal. I don't mean natural as something that happens in animal kingdom. Natural is something that is physiologically predetermined by nature. We don't walk on our arms, and we don't multiply through anal sex because our bodies evolved to allow for completely different function for mentioned body parts.</p>

<p>what are you even talking about? what's your point? anything that happens naturally=natural. Anything made by man or "shaped"=artificial.</p>

<p>Yeah? Why do we have an appendix, then? And why do we have the nictitating membrane?</p>

<p>Also, another example. approx. 15% of people don't have the Rhesus factor in their blood, and thus have negative group blood. Is this abnormal? How does this have evolutionary importance.</p>

<p>It's not like we NEED a larger population increase than what's in store for us. Maybe homosexuality is good for the human survival side of things.</p>

<p>First of all, I want to say I have nothing against the homosexual community, in case one mistakenly perceives that I do.</p>

<p>But there is something on my mind that I feel I should share (as usual.) Many philosophers, from Plato to Kant, have advised do not do something of which you would not make a law. Therefore, if one imagines homosexuality as a law, human existance would end, and that would obviously be devastating.</p>

<p>I am trying to think of possible rebuttals to this classic philosophical statement, and it is indeed difficult but not impossible. For instance, one can say you should have sympathy for the other, the other who is different. And that is what one is doing when being tolerant and open of homosexuals. And can/should one not make sympathy a law? It most certainly is moral.</p>

<p>And with this you have two conflicting laws, and with that you have a high potential for one very good debate :).</p>

<p>P.S. Some of you are being a bit too rash with your comments against the OP. I somewhat understand what he is talking about. He is taking into account human nature, and it is human nature for males and females to have sexual intercourse with each other for the sake of reproduction. However, one can also argue it is human nature to desire the different, to be distinguished, to think in a nonconformist manner--all of which one can use to describe the average homosexual. Thus, to the credit of the OP, one can in fact have a viable debate with his/her topic as well.</p>

<p>And what about women who can't conceive? Are they "unnatural"?</p>

<p>^^ They are considered to be deviations from the standard definition of the word, "woman," yes. Usually it's because of something that differs in their bodies from other women such as number of eggs or something physical blocking their ability to conceive.</p>

<p>And I might be wrong but I thought that the appendix had some function earlier on in man's history which is now obsolete but evolution hasn't gotten rid of them yet. (referring to TheOneCurlyFry's post a few posts ago) If it used to have evolutionary purpose, it shouldn't count for the argument.</p>

<p>this post makes me want to throw up...i'm gay, should i be killed then?</p>

<p>...or be deemed unnatural by the all knowing scientist?</p>

<p>Killed? Who said anything about killing anyone? This thread is debating the morality of gay-ness, I think, as well as the pro-gay argument. </p>

<p>Unnatural doesn't mean "should be dead."</p>

<p>EDIT: That's a different story.</p>

<p>I know. Things like these get me revved up and depressed though :-&lt;/p>

<p>Just so you know, gay people can reproduce.</p>

<p>good point, iin77! thank god for artificial insemination.</p>

<p>but that is not natural</p>

<p>well, it dependson how you look at it. no, if it weren't for the labs and such, no it's not natural. but, it's still REAL semen after all. and REAL children.</p>

<p>Rocks are natural, I don't think they can reproduce.</p>

<p>I still don't get the point. Why does any of this matter at all.</p>

<p>Plenty of excellent results for sociobiology + homosexuality.</p>

<p>Also, I advise you to read Steven Pinker.</p>

<p>People who are born sterile can't reproduce. Are they unnatural?</p>

<p>What do you define as "natural" anyway? Are animals "natural" enough for you? <a href="http://news.nationalgeographic.com/news/2004/07/0722_040722_gayanimal.html%5B/url%5D"&gt;http://news.nationalgeographic.com/news/2004/07/0722_040722_gayanimal.html&lt;/a&gt;&lt;/p>

<p>I get what the OP is trying to get at but it is hard to write exactly how he feels. The thing is, don't worry about it. I don't feel that being gay is "natural" (though that isn't exactly the right word to use) because if it was it would serve a biological purpose. But we can't really say that homosexuality doesn't have a biological or evolutionary purpose just because we don't know what it is. Just because we don't know what the appendix does, doesn't mean that it doesn't serve any functions. We find new discoveries everyday in the field of science so nothing is concrete.</p>

<p>My philosophy on being gay is: Be gay ALL you want. As long as you don't touch me or hit on me, I'm okay. And all it translates into is more women for me and every other guy. SO, keep having more gay sex.</p>

<p>I also have a problem with gay marriage, since marriage has a biblical philosophy about it, and we all know the bibles and gods stand on homosexuality. But thats another debate.</p>
