america, the white settler entity, is the global leader in race law.
White only citizenship, 1790 naturalization act. That's why only whites are americans. If you are not white you cannot be an american. It is a race based entity per its foundational citizenship law. You can be a neo-american (if you are desperate and devoid of any self worth).
Markle, she is mixed race, or mulatto (as the slave owning, racist, rapist, paedophile tyrant thomas jefferson referred to them in the advert he took out in the newspaper to recover one of his 600 runaway slaves). Prior to 1947 (when California overturned its ban on interracial relationships) it was illegal for her to exist there per the anti-miscegenation law which made mixed race relationships illegal (Nazi Germany and Apartheid South Africa had similar laws).
Markle is historically an illegal entity in america.
america was the template for the Nazis.
