I don't think Ben Stein hates America, and I am pretty sure he is not intentionally trying to destroy America (although, I could be wrong).
I think Ben Stein is paranoid delusional: He seriously believes that he is fighting against a new "Hitler-like" regime, with this movie.
He believes in Academic freedom (as do I, incidentally), but fails to realize the real reasons why Intelligent Design isn't making any progress in science: It makes no testable hypothesis, for one thing.
Until someone starts generating real science out of ID, it will continue to be kicked out of real scientific endeavors. There is no conspiracy. There is only scientific discipline.
