>That's why people have such an issue with it. I see that as a common claim, but given the lack of similar concern to non related individuals with recessive genetic disorders, even in cases where both parents have it, or in cases where parents have dominant genetic disorders, I find myself seeing this as a more after the fact rationalization than the actual reasoning. And as for the actual increase it risk, it seems quite minor compared to many other behaviors that increase risk which society doesn't frown upon nearly as much (with drinking and drug use being the notable exceptions that are routinely condemned).
