Here's a good argument: Marriage between ethnic groups makes for good looking kids.
Seriously, have you looked at some of the pics of our Grandparents who were purely Irish or Finnish or Prussian in my case? Not too easy on the eyes.
The mix of even those ethnic groups even among my European ancestry made for some nicer noses and less squatness.
Then I married a woman who is half-Puerto Rican and, Voila!, my kids are really cute.
