Keep the blood line pure .. or not !!

Since I'm a science nerd and all that.. I thought I would post something to that effect !! This site here had an interesting method of figuring out what the desi (for those of you who don't know what that is.. leave NOW!!!) intermarriage rate is. They use the Macy's wedding registry, and plug in a bunch of brown last names (all religious and ethnic groups),.. and come up with some interesting results. Although, at first I thought that this would grossly underestimate the real numbers, but it seems al though their assumptions seem OK !! Check it out here.
