We Americans, in general, are totally brainwashed by our media. Not all of us, naturally.
It's because we used to be able to trust them. Now, we can't.
Now, when clearly anti-Semitic media organizations like the New York Times publish unverified information from Hamas (or anyone for that matter) as fact, with zero journalistic effort to determine veracity, nobody blinks an eye. In the old days that would have caused them a lot of problems. Now? No worries, as long as whatever made up info they publish is anti-Semitic and anti-Israel.
