The obsession with flag-waving(or the obsession with not flag waving, which is the same thing) seems a bit scary. I'm with McGrath on this, it is perfectly blindingly obvious that there are people displaying this flag who aren't racist bigots. So to call them such sems to be needlessly trying to raise ordinary discussion into fighting talk.
Statement: some people displaying the Confedarate flag are racist bigots. Obviously true.
Statement: all people displaying Confedarate flags are racist bigots. Obvious baloney.
