This topic has been mentioned in passing in a few threads recently so I thought it would be time to address the issue head on.
Should incest be banned and is it wrong?
I'd say yes and yes.
All the supposed logical fallacies apply here:
It's depraved, immoral, leads to retardation, God forbids it, its unnatural and is just out and out weird. Many more issues of course as well.
Subjective, objective or whatever type of reasoning - it is wrong and should be banned.
When I say incest I'm really talking about close family members.
I'll try to be open minded here but I can't really see any justification for legalisation.
Anyone have anything to say on this?
Well, obviously I don't think Jews should practice it, because the Torah forbids us from doing so.
But as for everyone else, who are not so commanded, I don't see it as much of an issue. First of all, I doubt it is very prevalent: social conventions probably see to that. But in any case, in the past it was generally extremely taboo because of the genetic issues that repeated incestuous matches can create in breeding; yet today, when we have effective birth control, I am not convinced that I can find reasons for it to be illegal.
It may or may not be moral, but I am not a believer in using the secular law to try and codify morality, since that may differ greatly from culture to culture and individual to individual. Legally speaking, if the partners are of age to consent, I think the law has no business asking any further questions.
That said, I do tend to be of the opinion that incestuous relationships are probably not particularly psychologically healthy. They probably blur boundaries that should be distinct and foster self/other issues, codependency, and various other dysfunctionalities. Such relationships are probably best avoided.
But there's a big difference between what is unhealthy and what ought to be against the law. People have the right to make stupid choices. That's part of what freedom is all about.
