Depends on the “non white”.

Mexican Spics have an average IQ of ~90 That’s higher than Italian, Portuguese, and Spanish migrants had in 1919.

Spics also have a violent crime rate that isn’t too far above whites. Especially when you control for the younger age distribution of the population.

For example: In 1919 Lewis Terman, one of the founders of intelligence testing, reported in his book The Intelligence of School Children that the American-born children of Spanish immigrants had an average IQ of 78. For the children of Portuguese immigrants, the average was 84; Italians, 84; northern Europeans, 105; and Old Stock Americans—descendants of British, German, and Dutch immigrants—106.
