There are as bad in every fringe group school. People teaching various kinds of crap about any views they don't happen to agree with. Of course, the holocaust was a named genocide event, but people who deny it happened are actually making statements either about Jews, Germany, Nazi beliefs, or some combination of the three.

Still, this sets a dangerous precedent. If we can be imprisoned by a different country because of what we say in a third country, then there is no freedom of speech in any country.
