The fundamental problem with leftism is the belief that all groups are equal. We see variance between various groups of white people, and then we see variance in those sub- groups as well. Even siblings have enough variance between them that they could not be considered equal. For some reason to leftists everything must have a social cause. Blacks shooting each other in the ghetto, since we are all exactly equal, must be do to something holding them back, instead of personal responsibility. Because of this they are completely against the concept that maybe one race might just have lower cognitive ability and that this might contribute to criminality, except when it comes to blaming whites for all their problems, suddenly whites are the cause of all evil with no recognition between the various types of white people. Extremely evil people in my opinion.
