Tolerance is a one way street for Communists.
The MSM members are nothing but propaganda agents of the left (Marxists, Socialists, Communists), and as such they march in lockstep to the narrative they are given to promote. The structure of lies, distortions, and deception is at its most vulnerable state right now as much of it is being exposed to the American people. Having someone from the opposition, albeit one of suspect credentials, was a risk the principal agents weren’t willing to accept. Facts and truth are the left’s greatest enemy, and they couldn’t take a chance McDaniel might pass some along for their mindless minions to hear.
