Question

What change in immigration in recent decades appeared to concern Americans in the postwar year

Answer 1

Media world wide pushes non-white immigration on all white countries and only white countries, supposedly to solve some "race" problem.

Then they push intermarriage. Then they tell us that inevitably the last blonde will be born in Scandinavia in about 2202. This last is a propaganda technique used to demoralize whites into accepting their demise as an unavoidable fate.

And they call any white who objects "anazi who wants  to kill  sixmillion jews."

This program of elimination of my race, the white race is illegal under the 1948 UN convention on genocide.
