Here is an article from The Week, a liberal publication. (H/T Dina)

Excerpt:

You should really care that the German Ethics Council (a government committee) haspronounced that Germany’s laws banning consensual incest between adult brothers and sisters ought to be abolished.

Now, it’s not because Germany’s laws directly affect the United States; they don’t, of course. And even within Germany itself, the ruling party of Chancellor Angela Merkel has indicated that it doesn’t plan on following the council’s recommendation.

The reason why Americans — and especially American liberals — should care about the council’s ruling is that it gives us a glimpse of America’s future.

The German council’s position is based on the claim that “the fundamental right of adult siblings to sexual self-determination” overrides all other moral considerations, including “the abstract idea of protection of the family.”

Right now, the Supreme Court struck down the Defense of Marriage Act because they thought that there is no possible reason for defining marriage as one man and one woman other than “the desire to “‘disparage,’ ‘injure,’ ‘degrade,’ ‘demean,’ and ‘humiliate’ our fellow human beings, our fellow citizens, who are homosexual”. So does this rationale for allow gay marriage apply to incest marriage?

Well:

Well, how long before the majority wants to and believes it can get away with declaring a constitutional right to sibling incest?

Don’t laugh. As with same-sex marriage, the principle has already been established. In a notorious passage of Planned Parenthood v. Casey, the 1992 decision that upheld the constitutional right to abortion, Justice Anthony Kennedy wrote that “at the heart of liberty is the right to define one’s own concept of existence, of meaning, of the universe, of the mystery of human life.” Kennedy relied on the same passage in his majority opinion in Lawrence. The German Ethics Council expressed a similarly libertarian ideal of sexual autonomy in its ruling in favor of sibling incest.

[…]Note that the German Ethics Council also held that the prospect of a brother and sister producing children with genetic defects cannot be used as a reason to deny them a right to marry. After all, disabled couples are not prohibited from procreating under German law, even though they have a greater-than-average chance of producing disabled kids. The same is true, incidentally, under the Americans with Disabilities Act of 1990.

Indeed. If people should be allowed to marry whomever they “love” then, there can be no prohibitions on polygamy or incest marriages. Don’t they “love” each other just as much? Well, then those are both “marriage”, too. But maybe that’s OK with the secular left – they never liked that whole “morality” thing anyway. So long as the selfish grown-ups are happy, why should we care about children’s needs or social stability at all?
