People judge the media with their hearts rather than their eyes, allowing them to fit patterns that fit their biases and reject contrary evidence.
Kind of like a Flyers fan on a video replay of a non-goal.
My point being there's a bit of critical stuff, though not as much as pro-Israel stuff. But people choose to see either one or the other typically.
(Jewish-owned media aside, it also didn't help that the Israel/Arab divide was, for a long time, a proxy for the U.S./Soviet divide.)
