“Racist” is socialist code for “I’m losing control of my bladder because I can’t control your mind” ;)
“racist” is the favorite hate-word of the hard Left and their useful idiots in the GOP who help them attack people with the smear.
It’s usefulness is that racist is infinitely flexible and hard to define, so it can be applied to anyone who the Left and the GOPe want to drive out of acceptable society.
Their problem is that people aren’t buying it anymore. The average American is wise to the game and getting angry at the liars who play it. It’s not going to work on Trump. No one except the despised cabal of the political establishment believes it.
