Boycotting Israel because of its actions in the West Bank is not anti-Semitic any more than boycotting apartheid South Africa was anti-white. In both instances there are and were Jews and whites supporting boycott, divestment and sanctions. It was only the BDS against apartheid South Africa that brought down the apartheid regime. If Israel does not want to be the target of a world wide boycott let them heed the message. End the occupation. Get out of the settlements.
