"Perhaps its because two of the top officals at AIPAC have been charged with espinoge and passing classifed documents to a foreign power....just a guess."
First of all, the incident you mention is a relatively recent development, while the accusations of disloyalty made by the authors have been made all over the world against Jews for thousands of years.
Secondly, two officials being charged with espionage does not vindicate the academics sweeping claim that the "Israel lobby" as a whole, which they later clarify as code for "American Jews", are disloyal to American interests.
No one is being charged with espionage or anything close to espionage as the poster in #14 knows.
In fact the charges involved may be unconstitutional.

A truth lobby is needed to point out all the anti Israel and anti Semitic lies told.
