I agree with RastaGoddess but with conditions.
Nature doesn't have an agenda so to speak. However, if it has a "prime directive" it seems to be "life". However, part of life is death. We are born, yes, but we also die. So dying is also natural and part of nature.
By the same token... one must say that killing is also part of nature, as the lion hunts and kills his prey. The pray develops defense mechanisms to guard against this natural predator-prey relationship that seems so very one-sided. So one must say that it is natural for the lion to eat. Does this also mean that is natural for the prey of the lion to be eaten, and if so, why does it have the ability to run away? It too must eat. It too must live and reproduce life, not so lions can have more food, but for their own survival.
Make sense so far?
We all have an opinion how the world should work and perhaps that understanding is based on our observations. If the lion's food simply walked up to it and offered its neck the lion would never have developed the muscles, claws, teeth, etc. that evolution has given it to survive. And if prey suddenly stopped offering themselves but instead could successfully defend themselves then what might happen to the lion? Would it even be a lion?
Things in natural of often defined by conflict. There always seems to be "another side" whether we accept it or not. The truth is that some animals in nature have a range of sexual practices, including homosexual. It just doesn't define the species.
bad impression of an Australian voice: aye, look over there! It's the famous kangaroo along side its lesser known cousin, the fagaroo who is male but acts female.
There have always been sexual deviation; often based on access. I have a cat. Part of the reason I'm going to get her spayed is because when she's in heat she'll try to "back that thang up" on anyone in range. It's just that only a male cat is going to actually impregnate her. But other than that, are they going to raise those kittens together? Probably not.
Not only are there humans who are born with both genders, humans most likely started as a single gender. This is the only logical explanation why men would have nipples that serve no other purpose. You also have animal species that reproduce asexually. So nature just doesn't care. It has a lot to do with environment and in a prison you'll find a lot of people who don't care either. We have preference in our minds but hormones and nerve endings don't really give a damn.
And at the end of the day we are part of nature so whatever we do as a species is also part of nature and is natural. Just as dying is natural. I don't want to die just about as much as I don't want another man.... I can't even finish that sentence. And its okay to be homophobic. Just like its okay to fear death. Fearing death helps keep us alive. Fearing homosexuality helps keep us reproducing.
But when we reproduce too much... that's also a problem.
And so, it may sound weird and strange and wrong but I'm glad that not ever human is heterosexual. There are too many of us. And the more there are the greater the competition and more likely we will hurt each other and adapt in ways that make life far more miserable than occasionally being complimented by another dude.
And... the reality is that homosexuality between women is never going to be judged as harshly as homosexuality between men. I'm not going to lie. I don't want to see two men having intercourse of any kind. But two women is a turn on. And within the range of human sexuality there are taboos and fetishes. The more sexual repression comes from one direction the more it inspires sexual freedom in the other direction. So the more homophobic we are the more homosexuals we create by inspiration.
Do I think people are born that way? Some are. But I think many are socialized that way. They see gender neutrality in society and given the option to choose they choose the one they like best not the one that fits their genitals. I think many simply get confused and they try things and because hormones and nerve endings don't care they just assume that's what they are. They stop being simply male and adopt an identity that doesn't escape the box but merely puts them into a new one. Eventually that box starts getting popular among those who don't feel like they fit into the standard boxes and viola... homosexuals become a powerful source of influence in society. And by opposing them, at this point, we're just helping them recruit.
