Only a bold revisionist would make that kind of claim. Not only does this event represent a small episode given the bigger picture of atheist/evolutionist/communist syncretisms, but it demonstrates how Stalin's early drink from Darwinian assumptions played itself out in a brutal way.
Communists make fine revisionists of history to suit their claims and aims. Looks like you'd fit right in.
BTW, it wasn't just Marx who went to Darwin for approval. It was a group of die hard, Soviet atheists. (Thanks to PatrickHenry for the fine link.)
Hee hee. Darwin died in 1882. The Bolshevik revolution was 1917. But hey, why let some simple facts interefere with dogma?
