Why Is Gore Vidal Speaking At the Y?

Gore Vidal is scheduled to speak at the 92nd St. Y this October.

Why does Manhattan's premiere Jewish community center want to provide a prestigious forum to Vidal? 

Again. He spoke there at least one previous time.

If a writer had said the kind of thing about blacks that Vidal did Jews it's doubtful he would have been invited. 

There's nothing wrong with having speakers critical of  Israel.  Still,  at some point a line must be drawn and Vidal is a good place at which to draw it.
