We’re "white" in a certain sense. When a Mexican mixes with a white woman, the child often still appears 'white passing' or ethnically ambiguous like this woman.

It’s not like when a white woman has a child with a nigger (the child is visibly negroid) or with an chink, where the child inherits slanted eyes and yellow skin. Our genetics assimilate more easily into the broader European phenotype for some reason.
