Mr. Macdonald had recently been an organizer of the "Step Out Movement"-i.e., to step out of a hall where Vice President Humphrey would be speaking, in protest against the Vietnam War. This show offers a fast-paced duel between two longtime adversaries. WFB: "Well, Mr. Macdonald, why don't we try to isolate those forms of protest that you disagree with? You would disagree with, let's say, shooting the President?" DM: "Yes." WFB: "Would you disagree with forming the equivalent of an Abraham Lincoln Brigade to go to North Vietnam to fight on the side of the Vietcong?" DM: "Yes, I would." WFB: "Would you disapprove of discounting from your income tax that sum of money we have roughly spent on defense?" DM: "I approve of that. I haven't done it, however, because it occurred to me that the net result would be that they would get the money anyway plus a certain amount of penalties, which in effect would amount to more."
