After seeing the comments from some people here and elsewhere, I can see why so many holocaust museums exist and why many more are still needed. An atrocity like that, caused by socialism, can not be as forgotten as the atrocities caused by communism(more socialism). I think if we had more museums showing the atrocities of communism there would be far less deniers. It is fascinating how socialists love to deny their atrocities. National socialists deny the holocaust, communists deny Holodomor and many others. Kissing cousins of collectivism
