Punishing Deniers

I don't deny the Holocaust, though I might question the numbers, perhaps it was even worse than the law in various countries say it was but that makes me a criminal in their eyes.
Just as real scientists insist that everything is open to question (eg Climate Change) so real historians know that history is never 'settled' as new information and interpretations come along.
The problem with using the law to decide the history of the Holocaust is that that tendancy was always going to spread and so it has.

Hungary, that brave and friendly republic in Central Europe, has passed a bill equating Communist era crimes to the Holocaust and banned denying it under threat of imprisonment. Those denying, casting doubts on, or depreciating the crimes committed by the Communist regime will be facing from one to three years behind bars.

Russia Today, Communist Crimes Denial equates to Holocaust Denial


Apart from the problems that will give to the many surviving members of the former Communist regime, many of whom still believe that regime to have been positive, what next might be on the list?
Colonialism perhaps, or that every aspect of Slavery was the fault of Europeans and it's not just history; Climate Change skeptics have long been called "deniers" and many would like that to become a criminal offence, the evil EU already has laws forbiding bringing that sorry institution into disrepute.
Perhaps Mr. Cameron would consider a new law forbidding the denial that Labour governments always run out of other peoples money.

My initial doubts about criminalising a view of history that goes against the orthodox opinion have been vindicated and it can only get worse.
