Did you watch the video? Heilemann challenged him to name one instance then tried to run out the clock by talking nonstop. As anyone who knows Russell Brand would tell you he is not the type to allow that to happen. He was asked for one instance and he gave two, virtually the whole time Heilemann was trying to shout over him. Maher agreed with Brand, then tried to play a peacemaker as the discussion got loud and the time slot was coming to a close.
The whole point Brand made (and the one you seem to have trouble understanding) is Fox is prejudiced in one direction while NBC swings the other way, which is detrimental to the health of American society, as true journalists practicing true journalism, someone like Julian Assange, are rotting in authoritarian prisons. Brand said nothing - NOTHING! - in defense of Fox. You seem to be so locked into your tribalism you are incapable of hearing anything beyond what you’ve been hypnotized to hear.
