Non-Jewish support for Israel is heavily influence by our oh so unbiased media, which holds up the ADL as the standardbearer for Jewish opinion. I even think that the majority of Evangelical support for Israel is thin, based on false information from the media, political elites, and dispensationalist televangelists. Don't kid yourself, Jewish special interest groups and Jewish Americans in the media have a lot to do with this. There is generally a healthy and robust debate within Israel about their policies, but most people in America wouldn't know that at all. The things you read in Haaretz written by Jews or said by Peace Now activists would bring down a firestorm of accusations of anti-Semetism in the U.S.
I totally agree with this. We almost never discuss Israeli policy on Palestinian refugees and the Israel govt, unless it is to say that Muslims are bad and Muslims are terrorists.
Most Americans don't realize that Muslims are upset and attacking the USA civilians because of US support for Israel policies. Americans are led to believe by the media that we have to kill Muslims in Iraq and Afghanastan in order to obtain peace and stop terrorists. That is completely untrue, the only way to stop Muslim terrorists is to change Israel's policies and create a Palestinian Govt - separate and equal!
