I think blacks suffer from a deeply held inferiority complex. Everything in their life is seen not through a filter of right/wrong; but as a matter of Blacks vs White. No matter what a black man does (criminal, irresponsible act, stealing, etc) it is seen as a matter of victimhood.
Blacks can never progress, let alone get even with anyone else; if they view themselves as inferior at the very beginning. Every action on their part seems to reaffirm their inferiority.
A lot of the left’s appeal is just pure hatred of the other. Racists, no matter their color hate those of other colors - inferiors. So illerals always end up blowing themselves up with racism.
