I believe that the organized Jewish community of Madison - although it would be considered “liberal” - has had several disputes with a local group of pro-Pali radicals in the recent past. Yes, there would be some exceptions, but even the majority of “liberal” Jews would have little or no sympathy for the Rachel Corrie cultists promoting this play.
I’m wasn’t implying they would be hugging arabs or palestinians, but they do like to separate themselves from orthodox religious jews and zionist nationalist jews.
