I think variety is not only the spice of life but also the water, air and food. Being of a straight-laced one-race ancestry means you are PURE? PURE what? Sillybillies think there is such a thing and want to preserve it so their bloodlines don't get all muddied up with different colors. They don't know they were born muddied up as were all their ancestors and they will continue to muddy up future generations. I guess what they don't know won't hurt them. Right? I read that several racists in an effort to PROVE the purity of their heritage had DNA testing done and were crushed to find out they did indeed have the blood of blacks coursing through their veins. I wonder whether ALL WHITE RACISTS have the courage to get their DNA tested? They won't have to tell anyone the results. We all already know what they will be. :)
