So my family and I were eating, and incest became, albiet briefly, the subject. So that got me thinking: is incest wrong if it's consensual?
EDIT: A lot of people think that something like that is going on in my family. No. Just... No. The thought is just... *vomits*
Urgh, no, and its appreciated by all the clarification that this is not a case study, and is indeed all hypothetical, thank you for that confirmation there.
Anyway, its just not good, at all. Basically 85-90% of the time, its hetrosexual, and that puts into question the type of off-spring developed by such a union, which would likely have issues (beyond, parents = uncle/aunt + mum(mom)/dad). Deformaties, mental issues, I apologize if someone here reading this is from one of those unions, I mean what could you do if you were right? But basically, its just wrong on all levels.
The last comment on page 1 by 'Lyri' says 'Nobody should stop anyone from being together'. Well in this case, nobody should be in the unfortunate, uneducated situation, not to know the dire and horrible consequences of two people of the same blood, fornicating, and the laws make sense to prohibit such behaviour.
EDIT: courtesy quote, in case you'd like to rebut by statement

If I had a sister that I thought was sexually attractive and she was accepting of the advances, I'd screw her.
People are people, if you like them then do as you wish with them but you have to be aware of the consequences whatever they be.
Nobody should stop anyone from being together.
