This one doesn't seem to have made the news here, so we'll have to go to theWashington Post

The day after President Bush's State of the Union address, social studies teacher Jay Bennish warned his world geography class not to be taken in.

"Sounds a lot like the things that Adolf Hitler used to say," Bennish told students at the suburban high school. "We're the only ones who are right, everyone else is backward and our job is to conquer the world."

The teacher quickly made clear that he was not equating the president with Hitler, but the damage was done. A sophomore in the class had recorded the lecture on an MP3 player, and this week turned it over to a local conservative radio show.

Bennish, a five-year veteran of Overland High School, was placed on paid leave by the Cherry Creek School District on Wednesday, sparking an uproar over the issues of free speech and proper classroom behavior. About 150 Overland students walked out on Thursday to protest Bennish's absence, and the teacher's lawyer -- who met with district officials Friday -- has threatened a federal lawsuit.[snip]

The coverage in the right-wing US media, far from being concerned with freedom of speech (or freedom of anything), is apoplectic with fear that evil 'liberals' (dirty word in the US, even though, as George Clooney points out, liberals are usually proved correct by history) will 'pervert' American children.

First time I've heard 'teaching children to question' called that.
