From Weisberg's October 17 column, “The O'Garbage Factor”:

Whether the White House engages with Fox is a tactical political question. Whether we journalists continue to do so is an ethical one. By appearing on Fox, reporters validate its propaganda values and help to undermine the role of legitimate news organizations. Respectable journalists-I'm talking to you, Mara Liasson-should stop appearing on its programs. A boycott would make Ailes too happy, so let's try just ignoring Fox, shall we? And no, I don't want to come on The O'Reilly Factor to discuss it.
