Holocaust denial has been illegal in many European countries since shortly after World War II, because it is seen as motivated by an antisemitic or neo-Nazi agenda.
Now schools in the UK have decided to sweep the Holocaust under the carpet, along with other "controversial" subjects, such as the Crusades - because (according to the Historical Association) "they do not want to cause offence."
Some teachers dropped the Holocaust completely from lessons because of fears that Muslim pupils might express anti-semitic reactions.
One school avoided teaching the Crusades because its "balanced" handling of the topic would directly contradict what was taught in local mosques.
It is also said that he way the slave trade is taught can lead white children as well as black pupils to feel alienated.
A Government report said that too many teachers "play safe" and called for better training in how they should handle difficult subjects.

Must be damned confusing be a teacher of history today, but can't say I heard a lot about the holocaust or the crusades when I did it at school. Mind you, we've made up for it now...there's something about holocaust survivors or escape from persecution somewhere by Jewish people every week on Radio 4. I've reached saturation point and now just switch off...sad really as I once believed we should never forget, now I'm not so sure. Better to let wounds heal rather than keep picking at them I think. If there was a sign they were actually healing, I would say carry on, but there isn't one unfortunately, and Israel is a very sore point indeed for me, so perhaps I'm biased.
