The race card is almost exclusively played by Liberals and who was it that fought tooth and nail against desegregation and Civil Rights until the writing was on the wall so the at that time the Southern Democrats came up with the next best way to keep minorities down, Welfare.
It managed to break up families, excuse poor or no education, and they have blamed what welfare has caused on the GOP since then.
Remember the Southern Democrats started the KKK and only allowed integration when they were faced down by Federal Troops.
Calling someone racist is another tactic out of the rules for radicals, which say to put the enemy on the defensive because it will end talk about the topic at hand.
Liberal follow those rules quite well.
