>>21193438Genetics is actually pretty simple, it they look white, they are probably mostly white. A little bit of admixture from A or B-tier races doesn't hurt anybody (in fact some genetic diversity can be a good thing). The problem is adding millions of subpar F-tier niggers into white lands. It's easy to tell if someone is a nigger, even if only 5-10% nig, because nigger genetics are terrible, like being infected with a permanent heritable disease.
