Incest should not be illegal (meaning it should be legalized)

Here is my argument: In most scenarios, the government would need to violate the U. S. constitution in order to enforce incest laws. It was proved in Lawrence v. Texas(. http://en.wikipedia.org...) by the Supreme Court that the bedroom is a private place that the state has no authority to barge into if both individuals are of age and consenting. And if it does it goes against the 14th amendment of the constitution, specifically the due process clause(. http://en.wikipedia.org...), which is a guarantee of a fair legal process when the government seeks to burden a person's interests in life, liberty, or property. This would include the liberty to commit of age, consensual incest (excerpt from the due process clause wikipedea article: ""liberty" in the due process clauses broadly: "Although the Court has not assumed to define 'liberty' with any great precision, that term is not confined to mere freedom from bodily restraint. Liberty under law extends to the full range of conduct which the individual is free to pursue, and it cannot be restricted except for a proper governmental objective. "[12][13]"). This proves why incest laws are unconstitutional, therefore incest should be legalized. There is also the case for accidental incest, should someone be thrown into jail for having "sexual relations" with someone he/she didn't know he/she was closely related too? A significant number of incestuous relationships are accidental, it is surprisingly common for siblings to be raised apart from each other, only to meet later in life, fall in love, and even have children sometimes(example:. http://www.dailymail.co.uk...). Doesn't it seem unfair to punish someone who accidentally engages in incest? Also, the genetics argument (AKA the "they'll have deformed and retarded babies! " argument), the same genetic risk applies to people at or over the age of 40 trying to procreate, should those people also be prohibited from having children? And what about people with downs syndrome? Children of a couple where one of the parents has downs have a 25% chance of having downs themselves, that percentage doubles if both of the parents have downs. Should Jewish people be prohibited from having children too? This same argument could apply because 30 serious genetic diseases including ulcerative colitis are in higher concentrations in the Jewish gene pool. But I've already covered that all these people have the right to reproduce and have sex because of the due process clause in the 14th amendment, and it should also apply to incestuous relationships. What about same-sex incestuous couples? The genetics argument could not apply because same-sex couples are not capable of reproducing(not on their own at least). Certainly there are quite a few brothers and sisters that have experimented with each other as they were coming to realize what sex and romance was("playing doctor" would be an excellent example). Should they be thrown in juvenile detention for "sexual relations"(which I remind you doesn't always mean intercourse) between two consenting individuals of pretty much the same age? I think it would just create a lot more future criminals as juvenile detention is nicknamed "criminal school" because it turns a child into a hardened criminal. It doesn't seem like a reasonable or effective thing to do, just let kids learn about the other gender's bodies in a much safer, controlled environment than say, Internet porn, which would be the next most common way young kids(or at least young boys) learn about the body of the opposite gender. When it comes down to it, most people want incest to be illegal because of the arbitrary "ick factor". We evolved this way for a reason, if everyone reproduced with their brothers and sisters we all would be genetically screwed up. But it is no reason to keep two people who love each other and are of age and consenting from having sex or starting a family, it shouldn't matter whether or not they are closely related or not. I hope that the length of my argument didn't intimidate you, it sometimes does to other people and they don't respond. I would also appreciate it if you followed they general perimeters for the debate stated in my first post, meaning you post your argument this round and then in the third round you rebuttal my argument, and I will do the same and so on.
