The disengagement opponents finally hit upon a way to express their position, which is nevertheless a legitimate use of Freedom of Expression, and which does not arouse the ire of neutral third side parties.
They tie orange ribbons to the antennae in their cars if they are anti-disengagement, leaving blue-white or green ribbons to supporters of disengagement.
On Friday I drove to Jerusalem and back. There were several cars with orange ribbons, as well as youths standing in road junctions ready to give an orange ribbon to any car driver who shows the slightest interest in having one.
On Saturday afternoon, I drove to Netanya. This time, the orange ribbons were conspicuous in their absence. I saw exactly ONE car with an orange ribbon.
My conclusion: there is high correlation between disengagement opposition and degree of Jewish religion observance, as Jewish religious people do not drive on Saturdays.
