The case:
A man met his sister for the first time when he was 25 and she was 17. They fell in love. Later they found out, they were sister and brother. But they didn't care and became a couple. Later they had 4 children. 2 of them have a mental handicap.
Some time their grandfather reported their relationship to the police. The man was arrested for a total of 3 years. The mother wasn't, as she has a mild mental disorder, too. Some time when he was in prison they ended their relationship. One child stayed with the mother. Three were took from her.
Now this guy and his attorney went to higher courts, as they thnk that the law, which criminalizes incest is unlawful. But they failed court.
In Germany the paragraph 173 charges sexual (only vaginal) intercourse between relatives (first degree) with up to 3 years. It is justified with the amorality and that children have a higher chance to be born with disabilities.
The arguments of the lawyer (which I actually agree with, as they are rational):
-The sex had been mutually agreed on by both
-Noone was harmed by this (you can't really count the offended moralizers)
-It is ridiculous to only criminalize vaginal intercourse and not for example anal or oral intercourse
-If you condemn it, because there is a higher chance, that children become born with disabilities, you would have to forbid other groups of people to have children, too (for example people older than 40, having congenital diseases or people with other disabilities) That would be the same nazis tried to do, when they sterilized diabled people.
-If you say that the children are harmed by this, because they may be born with a disability you should ask the children, if they prefer to live with a disability or to have never lived at all
-Some people say incest is often not committed mutually and that this law protects family. But forced sex is already criminalized by the "usual" laws.
Of course it is weird, to know that people being brother and sister do love each other. But who do they harm by this? Noone. It is also quite rare, as there is some biological mechanism, which prevents relatives to fall in love with other usually. So it's not like that, that all brothers and sisters would fuck their brains out, if this law is lifted.
So what do you think?
Edit: Regarding the information about the couple some facts are not 100% accurate, as I was reciting from my mind. They met at the funeral of a relative and she was 16 and he 23 by then. One year later she had her first child. The other information are as far as I know right. Though the inaccuracies aren't really essential to the discussion.
Edit: Well, now I'm going to enjoy my weekend... I really enjoyed this diskussion :-) Didn't think, that there are so many people interested in such a case.
