Incest, a way of life?

My first reaction to incest is of disgust. My second reaction, is of disgust too. And my third reaction, well, its disgust again.

A German brother and sister are taking their fight 'for a sexual relationship' to court. The BBC in their website is following these proceedings and has attempted to explain the taboo that incestual relationships have. Many countries have banned incest and 'culprits' have been prosecuted. In this case, the brother and sister did not meet each other through their childhood and early teens, only later to meet and fall in love knowing that they were brother and sister.

Now personally, I cannot, just cannot comprehend how that happens. I have a huge family and many among them are smart and savvy guys - whom I haven't met for ages. But, even after meeting them, I can never ever think of getting into a 'relationship' with them. It makes me cringe. But then, maybe its how my beliefs have shaped me.

I know people cannot be forced into not doing anything. And the more you try to impose restrictions on them, the more they want to do it. Especially when it comes to supposedly 'moral' issues like these. No one accepted being gay or lesbian earlier. But now its come to be a part of normal society. But where do you draw a line? Although I would find accepting incestual relationships very distressing, I cannot choose to clamp down on a fellow humans' personal liberties. Which is why I find, people being jailed or prosecuted for this 'crime' really silly.

We're all animals yeah? We're just behaving like we're genetically programmed. Right?
