All of them.

It is a sad thing that you can state this without most people even twitching an eye while had you stated you were a national socialist everyone would shun you. The sad thing does not lie in the shunning of the national socialists but in the fact that its internationalist brethren in socialism are not treated in a similar fashion even though this ideology has destroyed far more lives than the former. Marxism-Leninism and its spin-offs - Stalinism, Maoism. Juche et al - deserve to be in the same corner as national socialism but alas, these ideologies thrive in places of education and as such children and students are mostly or only told of the evils of Nazism. I can see this happen at my daughter's school where they've focused a large part of their curriculum around just that, including a visit to Auschwitz. I proposed they'd also spend some time on studying Solidarność and its struggle against the Soviets given that they were in Poland where the beginning of the end of the Soviet Union took place but this was not to be.
