Several readers have added some names to the post-PC list of current entertainers. Item One:

Don't forget Ali G.  Although I wouldn't necessarily say he's inoffensive, he deconstructs pre-conceived notions about identity as brilliantly as anyone on your list, and in ways that the older generations (as represented on his show, at least) consistently fail to understand.

Agreed. The "Little Britain" series deserves an honorable mention. And then there's Sarah Silverman, who has pushed the post-PC envelope about as far as it goes. Post-post-PC?  Check out her new movie, "Jesus Is Magic."  But not if you're squeamish in a left or right sort of way.
