Just so that I understand....and please correct me if I'm wrong....

Jewish leftist groups support a boycott of Caterpillar because it's equipment is often used by the Israeli government to illegally destroy Palestinian homes and farmland. Yet...

Those same groups support providing Hamas with millions of dollars which they often use to provide arms to it's members that actually kill, injure,  kidnap, etc. other Palestinians. (Not to mention their use of weapons to kill Israeli Jews or the force the slow reversal of women's rights).

I urge everyone who can to watch or record Frontline tonight - Looking Inside Hamas: Search for Martyrdom, Hatred of Israel.  It should be noted that Frontline is no right wing mouthpiece as can be seen by their show on the danger of the radical Israeli settlers.

On a separate note, and I'd like to find a more independent source for this, one may not be safe speaking Hebrew on the streets of Berlin.  And it ain't neo-Nazis that are the problem.
