Hypnosis can be applied to those who have a preconditioned agreement with how they will behave when hypnotized.

In this way, the news media in the US has hypnotized many Americans. They choose to believe outright lies. This is as it was in Germany in the Thirties. But Obama is not Hitler.
His values are different.

In Obama's case, people want to believe that what he says is reasonable and true. There is an unwillingness to analyze his statements without partisan rancor.

He has a soothing intonation that makes certain people feel good. It's reminiscent of
a preaching style found in the pulpit.

BTW, Reverend Wright was right in his assessment about the US even if he was a preacher.
