the problem with 'cousin marriages' in the Pakistani community is that they are so common they occur again and again in someone's blood line, it's not just a one off event of say me marrying my cousin. That would be unlikely to result in recessive gene disorders because it would be a one off, however if my mother had married he cousin and my grandmother married hers that makes it a great deal more likely, so it's more of a culture specific issue than something which applies to the whole population, thus i'd be unwilling to advioate changing the law.
