Neglects to mention Black Panthers, the Ferguson (et al) mobs, the desecration of Christian churches, the LGBT indoctrination in schools, etc. which are fueled by revenge.
IMHO, there is a much larger percentage of the American demographic influenced by relative morality and comparative religious perspectives than Christian zealots seeking vigilante-ism.
Lots of angry closet LGBT, blacks, Latinos, even Zen-Buddhists out there who would just as soon exact vigilante justice at the ballot box as they would execute known murdering street criminals.
