Anecdotal but my experience on more than one occasion as a youth. Blacks are not good or willing fighters (except in the ring). As a kid who got into his share of fights I can testify blacks will not fight one on one unless in an inescapable situation but will gain courage when among a group of their own race. In the case of Obama, his "gang" is the media.
For being “not very black”, he sure seems to hate white people.
