I'll grant that ethnicity is indeed real (even if there's an attempt to brainwash people into denying it), but as far as laws are concerned, everyone must nonetheless be treated equally, regardless of ethnicity:

Should e.g. the USA have different laws for ethnic-Europeans, ethnic-Asians, ethnic-Africans, ethnic-Americans, ethnic-Arabs/Hebrews, etc., depending on the ratio of what kind of blood each person has?

Should there also be different laws for Orthodox Christians, Catholics, Protestants, Hindus, Jews, Mohammedans, etc?

Perhaps you consider that only First Nation ethnic-Americans (Navaho, Chickasaw, Comanche, Delaware, Iroquois, etc.) are actual/real 'Americans'.

However, if you were born and raised in the USA, and even fought for their military, must you not also be considered 'American', even if you have European, Asian, African or some other foreign (non First Nation) blood in your veins?

It does seem, does it not, that it's unjustifiable for a state to make ethnic/racial and/or religious distinctions in its laws, and, more importantly, it seems ... unjust.

PS) In this exchange with von Hindenburg, even Hitler seems more measured/reasonable than you.
