Why are many Americans so ignorant regarding the racial term White?

They are quick to defend Jews,North Africans & Middle Easterners and identify them as "White" while at the same time refer to all White southern Europeans(Portugal,Spain,Italy,etc.) as "less" White or "mixed" race people! I guess the Jew controlled U.S.A. country is doing a great job in brainwashing the few pure blooded Whites(non Jewish White Americans that are of pure European ancestry)that the Jews,North Africans & Middle Easterners are "their" people. All Whites of Europe(regardless of European country of ancestry)belong to the same race which is White.As true Whites that we are we must be united and not allow non Whites to contaminate true racial facts,Just remember as un united Whites we will perish & fall defenseless against a consciously anti-White "rainbow coalition" that aims to bury us all.
