I think it's a little weird for C-Watch to characterize a pro-Arab, anti-Israel view as "extreme left wing." Many anti-semites will ally with any other political position that they can to bolster their position; this includes radical Islamists and others who hate Zionism in principle. Given this, they may claim to be left wing when "I pity the poor oppressed Arabs" is an argument that works, and they may claim to be right wing when "Canada for the Canadians, blacks and Jews get out" is an argument that works. It all comes down to hate, not left vs. right.
