One of the things TV talk show hosts like to do on mainstream media is to get some poor White “supremacist” kind of guy, and make him look stupid. It has been done since the 1960s, and usually the victim walks into the trap and, unprepared for the totally unfair attack, is eaten alive. Of course, there is a mandatory hostile audience assembled, for what does one expect in a racial war?
The recent attacks on White nationalists have involved getting the victim to submit to a DNA test, then reporting on the findings, which, of course, will reveal, a large percentage of “African” genes, defined as genes commonly associated with African descent. If not, they choose someone else. Here are some articles where a White nationalist is presumably “discredited” because his genetic ancestry is 86 percent European and 14 percent sub-Saharan African:
