Every death under socialism is attributed to socialism. Every death under capitalism is attributed to individual failing or inevitability. Please follow the rules.
You mean the National Socialist party? Heh, no I don't think that Nazis were Socialists, but NSDAP certainly used socialist rhetoric to broaden the appeal of their party. In fact in Mein Kampf, Hitler makes the argument that Marxists merely hijacked Socialism and corrupted it.
In any case, I don't want to entertain horseshit. It turns out that if a significant part of your political ideology is about elevating one group of people at the expense of another, mass starvation and mass murder is an inevitable consequence.
The whole point about spotlighting catastrophically bad ideas is that hopefully nobody gets the stupid idea to try that shit again. Except here we are.
