If this is aimed at me, then please define your terms. I've done plenty in the trenches, from street corner to homeless shelter to church basement to Ivy League auditorium to CNN and back again. I will confess that I've not played the campus Leninist card (an important card, I think we'll all agree), nor have I promoted obscure films to manure the ground for revolution. So, perhaps in that sense, I am indeed a "shirker."
