Most states in America have either outlawed or restricted the practice, as has China, Taiwan and both North and South Korea.Professor Spencer, an evolutionary zoologist, said these laws should be repealed, especially in America, where he said they were drafted in a way that discriminated against the rural poor and immigrants: "Neither the scientific nor social assumptions behind such legislation stand up to close scrutiny.Instead, advocates of laws against cousin marriage appeal to science. I can't find anything in the Bible about this subject, but we are taught that it is not right to date your family.Specifically, until the 1860s or so, first cousins commonly married in Europe and the U. Nonetheless, the practice soon fell out of fashion in the United States.

You can't just say the practice in question is icky.
Technically, this does not prohibit marriage to cousins.
The fuller prohibition has come partly from a desire to keep as far as possible away from something that is spoken of with such serious warning in scripture. As our society has become more numerous and diverse, it has become more repulsive to us to marry close to family. Cousins usually share a common set of grandparents (though it can be only one grandparent) and one-half of the genetic pool.
