Wow! Before 1946 people can not become US citizen because they were not White ? That is so bizarre! Why today's white Americans are so proud of their forefathers!! It is a real shame for a civilized nation! I think it is not so Civilized nations after all! That is why may be a crazy man can just walk to into an elementary school and shoot all innocent kids and they call it, No, It is Gun rights! Our beloved 2nd amendment! What a shame on you white folks!
