Ilan Pappé, professor at the College of Social Sciences and International Studies at the University of Exeter in the UK, director of the university's European Centre for Palestine Studies, co-director of the Exeter Centre for Ethno-Political Studies, and political activist explain why Israel is not a democracy in this Mideast Monitor article. Israel has a political cast system, and just because the lower cats can vote, that does not mean they have equal rights.
