I've heard it said time and again: Black men are cowards and will attack only in packs, and only against individual or greatly outnumbered victims. Seems a credible case but check out this video for confirmation. In it you'll see a White man pretending to be a zombie. Large black men, some in gangs, flee before him. Betraying not just cowardice, I suppose, but also ignorance and stupidity on an epic scale.
