My thoughts...
Well I do find the concept of incest to be creepy. But I think mankind has much more serious issues at stake: war, povery, sexual/physical/emotional abuse, AIDS, the list is nearly endless. I would say incest (apart from child sexual abuse and similar issues) is fairly far down on humanity's list of problems.
To be honest, I was always attracted to one of my cousins, but I never acted on my urges. I suspect she didn't feel the same way, and even if she did, I wouldn't even so much as kiss her lips. I don't think I could ever forgive myself if I even tried to do that.
Nevertheless, I still do agree that incest is bad, but I think it's no worse than homosexuality. It's funny that in some cultures you can be jailed or executed for homosexuality but incest is accepted practice, and in our culture incest can get you jailed for like 25 years but homosexuality is accepted practice. Just a couple of facts for you to think about. I agree that if one is wrong, so is the other.
However, I think if you get with like your 9th or 10th cousin it would be just fine. There has to come a point where you're distantly enough genetically (and in whatever other ways are important) where your "relation" with that person would no longer be an issue.
What I absolutely have a problem with, on the other hand, are parents that take advantage of their young children and sexually abuse them. I think we can all agree that is one of the most heinous and sick crimes: child sexual abuse. But as far as consensual incest, count my vote as no, but with perspective that there's alot worse out there - infinitely worse.
