Yeah..
BB, don't try to explain to commies/progressives what a practical application of their ideas means.
They will never believe you because their mental conditioning, which makes them Marxist, is preventing them from seeing what it is.
If you show countless examples of failed Marxist experiments on real people, they will counter with feeble excuses like, "Oh, but their economy wasn't modern enough, or they were just backward this or that =, or that because some people did it wrong."
They don't understand it in the way a normal person would - experiment was done on different races, people, cultures, and economies, and all proved without a doubt that Marxism is a totalitarian evil sh't.
They see it as - the other Marxist has done something wrong, but I and MINE people will get it right -0 because we are great and our egos are even greater, narcissistic' delusions nah - that fascist talk.
