Yep. But to be fair, most theories get thrown in the bin after multiple failed trials. Fascism was tried at a couple places but after Oppenheiming and explaining to certain Austrian painter how and why that theory is trash, it’s stayed at it’s rightful place as a fringe ideology for attention seekers and lunatics. Why communism is still a valid theory after multiple failed irl trials and genocides inherently linked to the theory, is beyond me. But I view communism as more of a cult than a real political ideology anyway.
