So what is the difference between "white" and "caucasian?" The title on my home has a restrictive covenant which says that nobody of the "white OR caucasian race" is allowed to reside on the property. I can actually trace part of my ancestry to the Caucasus mountains (the Khazars), but the rest of my family were those meant to be excluded by that restriction. Yet, how would someone prove that I had violated it? My wife, who you would consider "Black" also has some ancestors from Europe you might call "White," although not from the Caucasus; so would that qualify her as "White" enough? You can be either white OR caucasian to avoid the restriction, after all.

Or, we can just recognize the reality that there is no such thing as "races" of human beings. As this article points out, the very idea of "races" has no basis in real science. There is, however, the delusion that we are divided into arbitrary "races." That sociopathic delusion is called "racism."
