I wasn't aware of it being illegal. Maybe in some cultures, but I am pretty sure its not illegal here in Canada; its just massively social taboo.
I said "no" in the poll because it doesn't really seem to be something that should be legal or illegal, or even mentioned when law comes into play. As for social law, I have no say in that, so /shrug.
What do I think of incest?
I've had a few cousins that I wish weren't cousins, lol...
But either way, I think incest is inherently wrong. The whole point of life and procreation is to spread your genes and achieve genetic immortality (as far as I see it, when boiled down to the bare facts). When you mate with someone who shares many of your genes (enough to be considered family, and to be considered incest), you are not really spreading your genes at all. Besides that, your child will likely have alot of birth defects, and have to deal with people knowing that they are the product of incest (unless the child is raised in a society where incest is ok)
Psychologically, I still think incest is inherently wrong. Why? Because when you join a relationship with someone, both of you should grow and develop into better people because of each other. This can't really happen if you are related to them. Hell, I know alot of people that have dated/married the person they grew up with, and very few of them are happy, lol.
This post sums up my TL;DR post:

Having a sexual relationship? Knock yourself out.
Having children? No.
Edit: Forgot to mention the consent part.
If they are both adults, and they both consent, then why the hell not.
