Lets asume that Rabbi Metzge should have approached the community more differentially than you say he did. So, here is a guy who wasn't differential but made an appearance of support, an appearance where he was trying to tell Israelies that attacking an Islamic place of worship is unacceptable. Here is a guy who tries to package his message in a way that is meaningful to Jews. In this context, the citizens of Suad threw stones?? Why is it that the only way Pals can deal with anything they don't like, and I mean anything, is violence? Why can't they talk and criticize, not in response to the araonists that burned their mosque but in response of an allegedly insensitive but nevertheless peaceful individual who seeks to support their cause and empathize with their pain.
