Before I even start let me just say this is a Serious topic and if you're just gonna come in here and say "Eww that's nasty" or "Thats weird", get out now. Now here's my take on this, since I'm on my Wii don't comment on my grammar or if I double post (The Wii has a 2000 character text limit apparently)

Incest is when Family members or Blood relatives have a sexual relationship. Incest is almost universally frowned upon and pretty much taboo in most societies. Now I'm not writing this topic because I myself am incest, I find all my family members disgusting through a sexual standpoint but if people WANT to do it, I say "Whatever do what you want.". I do not agree with all incest, as most cases of incest are usualky some form of molestation, usually by horny fathers (You know the type) especially here in the United States. That kind of life scarring crap is totally fucked up. But what I think is ok is if a Daughter/Brother/Sister, whatever actually WANTS a relationship with another family member, fine. If two people within a family love each other like that, why not? You find love in strange places after all. There are circumstances you have to consider, people have rough lives and sometimes family members are the only people theres for the person.

Inbreeding is probably the biggest issue when you talk about Incest. Family members having babies can result in less then normal children, to say the least. This is a problem, and I think that most incest couples acknowledge it and are willing to NOT have children but thats probably a minority. But the majority of a already minor sexual preference is still not big. I do not agree with this as our society is already "unique" enough. Now since I'm running out of characters lets wrap this up. I can clearly see that I contradicted my argument with the Inbreeding thing, as that is the basis for some arguments. But I think the main problem is most find it disgusting, immoral and such, but if it doesn't affect you...
