Karl Marx had a unique talent to convince people to pursue a path that should have obviously appeared to be the wrong path. For example convincing anarchists that a Large governmental structure would eventually lead to No governmental structure. Unfortunately for the followers of Marx, the world eventually discovered that said anarchist made poor workers and even poorer governmental planners. That strategy was designed to fail from the start. He basically convinced people who lacked the talent to manage a large government, that they would eventually have such an efficiently running government that the state would eventually disolve. My guess is Marx knew they would fail all along. The question now is did the creator of the Koran also know such ? Imagine convincing people that by killing innocent woman and children, they would eventually be entered into paradise.
Concerning the left's attempt to erase our history, we should take it as a compliment. Someone once wrote somthing similar to the phrase: Losers spend their time rewriting history, while the winners are spending their time making history.
My Dad said in the 60s that Marx knew exactly what he was doing--he was a superlative con artist that used envy to fuel hate for those that possessed more to take over a country that he and his minions would rule. He suckered the masses into letting the few rule the many with an iron fist. The masses ended up with nothing, while the few on top had everything.
