Should incest between consenting adults be a crime?

[Mr.Obvious]

1. I'll be the first to admit I don't have any actual numbers on this. But I don't think here in the west, at least, that it's a common occurance. At least not past puberty. But I could be mistaken.
2. Yeah, it is. As I said, were two related people without any grooming come to want to indulge in such practices, it'd be completely their business. And they shouldn't have to worry at all about anything I feel about the subject. But aforementioned grooming is like an arranged marriage, be it between family members. And that is the biggest problem I have with the incest-question. And I just meant to show you how hard it might actually be to point out the actual grooming, brainwashing or influencing taking place might be. For example, is it concidered child-abuse if a family sets up two cousins to be married when they come of age, starting at their birth? Shouldn't it be? And if so, how do you prevent it without  tresspassing on 'people's freedom of choice'?

1. There have been studies that show attraction between cousins is common at puberty

2. I'm pretty sure grooming your kids into incest is would still be a crime even if it's hard to detect and even if incest between consenting adults were allowed .

1. Yeah, but I was talking about past puberty. As a child you don't really know what love and even attraction really is, I feel. And in puberty, your hormones messing with you and what-not could have you jumping a snow-man if things got desperate enough.
2. I'm not saying it wouldn't be.
