Okay ....
..was just kidding..don't worry.... And even if it was the case , after we would get the "under-categories"....the ones of the mixed race who have long feet and the ones who have short feet, and so on....
So , don't worry the Human Mind would have always enough imagination to classify people ...just because making selections is a part of the human nature....Look at the young babies : they are not kind and generous at the origine...they learn to share and to be kind with the education ..it isn't innate, inborn...
