There is no anti-semitism on the left.  It was the left that was the first to protect and shelter the Jewish people while condemning the explicit bigotry against Jewish people that fermented on the right.  The simple fact is it is now easy for these came clueless types on the right to call people on the left anti-Semitic for doing the right thing and defending the Palestinians.  Don't worry the left would have did the same if it was the Jewish people being murdered and had their land stolen.  There was a reason Israel was the last country to defend South America.... They did not want to be the only country left in an apartheid state...which they now are.
