Do the deaths of little people not matter as long as the great leap forward is achieved? Do you think the statist socialist places weren't doing socialism hard enough, or will you make a 'no true Scottsman' argument and claim they weren't doing it right? It's just that every single time... every. time... every. single. time... it ends in rivers of blood. The useful idealists are liquidated the moment they object.
I'm not going to make a "no true Scotsman" argument, because it's irrelevant whether what they were trying to achieve was "true" socialism.
Socialism, communism, capitalism—none of those have anything particular to do with mass state-sponsored murder. If you think socialism—things like Medicare, Social Security, and the Earned Income Tax Credit—can in any meaningful causative way lead to millions dead, then you're the one who's deluded.
