All debateable of course, but that is why Hitler is so outstanding.
I think that's an unfortunate turn of phrase Lizzie.
I don't think so as he is outstanding amongst modern megalomaniacs for his ability to manipulate, coerce, almost hypnotize massive numbers of people (just read the accounts of those who met him, heard him, and gathered at the infamous Nazis rallies) to commit to not only war but mass genocide, and an evil rarely seen at such magnitude. Stalin and Mao were responsible for terrible acts to so many of their fellow countrymen, but Hitler targeted men, women and children, across many nations, just because of their ethnic background or physical ability, with experimentation carried out on some of them to find out what caused their "flaws" or "differences", before gassing them. He managed to convince tens of thousands of what would have been previously considered well balanced people to fall into his spell and commit to such evil it is hard for us to understand or forgive. Oh yes, he was outstanding, but for all the wrong reasons that can rarely be contributed to one human being, that even as a Christian I find hard to forgive even if I have the right to do so.
I know you like to give the Soviets/Communists/Marxists/Maoists a free pass on their atrocities but why does Stalin's treatment of Poland and other European states differ from what Hitler did? This was not within the pre-1939 USSR, but where the USSR invaded Poland and annexed other Eastern European states.

In respect of what the Soviets did to Poland in 1939, in collusion with Nazis Germany, was undoubtedly a terrible act and in line with how Stalin, yes, could be equally cruel and murderous as Hitler. But, after 1795 to 1919 (the end of The Great War) Poland was partitioned and ruled by the Kingdom of Prussian , the Russian Empire, and Austria. Hence both Hitler and Stalin considered (very wrongly!!) Poland and it's people part of their domain. Hitler, of course, considered it a justified right to absorb Poland into the Third Reich, along with Austria and the Sudeten Lands (not forgetting Alsace and Lorraine). It was a murderous time from September 1939 to the Summer of 1941, but then Hitler excelled himself in evil and invaded the Soviet Union, directly murdering 100's of thousands of Russian civilians, with up to another 630,000 dying of starvation and illness. Of course upwards of 25 million Russians are believed to have perished overall due to WW2.
So yes, I cannot ignore what Stalin did to Poland, then to the Russian people themselves, including hundred of thousands of his own troops, both before, during and after WW2, but as I said before it was Hitler who murdered, or caused the death, of not just German civilians, but so many other nations peoples.
