this is a half truth. yes there are caste based genetic variations. but the mixture is soo minute its retarded. like how here for the longest time we didnt consider italians or irish as white. yes a variation exists but it its not enough to enact laws for a human to be born into with no choice of their own. if you gave any brahmin a chance to get with a white chick that whole caste arguement folds like a lawn chair
