[ Psychology has a long list of solemn statements that became clueless when you scratch a little, even falling in pseudo-religious and self censoring BS sometimes, but the possibility that "my evil twin" would be planning a massive killing with my bare hands is really remote, so I'm not really worried about that. In any case, thanks for your interest ].
Of course If racists really would not wanted to kill other people, they seem to have a long history of "oops, I did it again" unfortunate moments. Those people have a really bad luck
