No, he was talking about the tactics of perception -- a black conservative might well be more effective in such a debate because of the "I've been there" factor.
Now of course the leftists have slathered this stuff with hypocritical pseudomorality to the point that they probably believe whites have no right to talk race issues with blacks. Matt's coming from a different perspective: understand your opponents and be willing to use their best tactics when it doesn't conflict with your core principles.
I ambled up between sessions and asked Matt if he'd read Saul Alinsky's Rules for Radicals -- Alinsky advised, among other things, staying within the experience of your group and working to maneuver your opponents outside their own areas of experience. He had, of course.
