I happen to know a few Arab-Canadians who support Israel. Some of them are very devout muslims. I give them the benefit of the doubt. The point is that people vote with their feet. Some (not all) of the Arabs who live in Canada do so because they value the Canadian way of life (ie, democracy, multiculturalism, snow, whatever). For whatever their reasons are, the like in Canada and America because they like it better than the Arab countries. So when I see an Arab-Canadian who supports Israel, until they do something to suggest the contrary, I take them at their word.
