Jewish American Professor and Political Scientist Norman Finkelstein.
Apparently hates America. Wow this dude is legit. I've never heard of him until now. It appears he is a Jewish intellectual that is very vocal about Israeli / Palestinian politics. He tends to side with the Palestinians. Here is a quote that blew me away, but I think it's an excellent quote:
"Every single member of my family on both sides was exterminated. Both of my parents were in the Warsaw ghetto uprising. And it's precisely and exactly because of the lessons my parents taught me and my siblings that I will not be silent when Israel commits its crimes against the Palestinians."
