People see the families of racially motivated, anti-White stabbing victims talk about how "<x> wouldn't want this to be about race" and "the bigots politicizing this are the real problem" and they wonder who would do such a thing and how you could you let your family die without taking vengeance.
This guy is primary example of someone who would behave that way. A nigger could murder his family in front of him and he'd call it an isolated incident. Guys like him are totally mind broken.
Yuri Bezmenov would call someone like him a "Useful Idiot". You can show this guy as much evidence as you want, show him photographs and videos of niggers murdering people and throwing babies into bathtubs full of boiling water, he'd still deny anything was going on. The only way to deal with people like this is, in Yuri's own words, to shoot them.
