I am not talking about economic systems. YOU chose to call your ideology "Marxism-something". As a result, I am judging your credibility based on the past track record of Marxism. If you remove the word "Marxism" from your ideology (and the faces from Marx to Maofrom your banner) , I will no longer do that
The failures of any current system do not make an alternate proposed system more credible.
They make it more desirable, maybe, but not more credible.
The first time? Communist Russia, Communist China, Communist Viet-Nam, Communist Laos, Communist Cambodia, Communist North Korea, Communist Cuba.
That is at least 7 attempts
If I count Communist Poland, Communist Czechoslovakia, Communist East Germany, Communist Romania, Communist Bulgaria, Communist Hungary, Communist Yugoslavia + all the African shitholes that also tried the thing, that makes over 15 attempts.
