I found myself once again singing at an antiwar rally two weeks ago, and once again being confronted by a red-faced white man with an ominous hand-written sign reading, "9/11 was a lie." Most of the crowd was filing off for the post-rally march, aside from a few of my loyal fans who were sticking around for the rest of my set. Among them was the red-faced man, apparently not a fan, who walked towards the small stage with the wild-eyed certainty of a zealot.
