Pitchfork Tillman! The Red Shirts! An excellent read from Damon Root in Reason. Memorable quote:

“If the colored man continues to lend himself to the work of tearing down what the white man has built up, a race hatred worse than any ever known before will result. Caucasian civilization will serve notice that its uplifting process is not to be interfered with in any such way.”

That’s Sam Gompers of the American Federation of Labor. The union bosses haven’t changed much since then, in my experience, and neither has the rest of the Left.
