But those things are not biologically driven in us. Sex is to reproduce.
Sorry, but no. It is interesting that humans are one species that are not biologically driven to reproduce. We are merely biologically driven to have sex -- there is nothing in males or females that makes us only have sex when reproduction is possible like in many other species.
Sure, it can also be for fun and for connection but those things go against our amygdala.
Again, science is showing this to be false. Rather, current brain studies are finding differences in the hypothalamus and amygdala between homosexual men and heterosexual men, as well as between homosexual women and heterosexual women. As such, homosexuals no more "go against" their amygdala than you go against yours. In fact, it appears that changing gays to have sex with the other gender is going against their amygdala.
The point is solid, we are hard wired to reproduce.
And again, in humans this is false. In cats it is true, ever see the way tom cats are all drawn by a female in heat? Further, in humans an infertile woman still desires sex and others can still desire her, even infertile males and females desire sex. In many other species, if a female is infertile then in almost all cases males do not have a sexual interest in her.
Wanting sex for any reason other than to reproduce goes against that basic, ancient instinct. That doesn't make it wrong, but it does make the point that we are basically genetically heterosexual a sound one.
Human history shows this to be false. Humans throughout history have wanted sex for any number of reasons, though love is a typically stated reason. I've never seen a play or movie where a person said, "I feel a need to reproduce, so let's have sex". Rather, reproduction is more often seen as an unwanted side effect.
And if we are supposed to accept homosexuality because the penguins do it, I'm going to eat my babies so my wife will want to have more sex with me, after all, mallard ducks and lions both do that.
I didn't see unnatural. The implication was that reproduction is what our genetic code states, you editorialized with the unnatural.
Ludicrous argument. It is amazing how Christians will talk of how homosexuality is not "natural", then when shown that it is natural they or another Christian will bring ask "do we kill our young since it is natural, too?"
Whether something is natural or not does not make it right or wrong. We use corrective lenses to improve eyesight, we drive and fly in metal machinery which actually harm nature; yet none of these things is considered immoral.
And if we don't want to emulate animals, as you seem to be suggesting, then I guess we should not have sex at all, especially to reproduce, and quit eating since Mallards do that to -- and obviously everything they do must be evil. Or so your point would appear to claim.
Rather, the truth is we do things based partially on biological wiring, such as the urge to sex. Though we use our reason to both temper our biological urges (we don't have sex everytime and everyplace we feel excited) and to attempt to reject urges we view as harmful to ourselves and others. Smokers will often try to stop smoking since they know that it is harmful to themselves. We temper our rage and anger (or at least most try) so that we don't murder or inflict injuries on others. Your problem is that there is no evidence homosexuality causes any harm, at least other than your interpretation of a religious book.
