Yep, had a lib tell me this week there never has been Communism. A true believer in some socialist utopia that only exists on paper.
The McCarthy "witchhunt" was misguided because although there were people calling themselves Communist and although there were governments calling themselves Communist, it was "wrong" to persecute "the Communists" because (A)they meant no harm, (B)they had good intensions, and (C)the foreign power they served "wasn't really Communist anyway, it was State Capitalism".
And Islam isn't really the death cult founded by a conquering warlord...
Your lib friend is right. The left has never succeeded in actually instituting Communism. The steps are, Socialism until the time is right, and then a full Communist Utopia.
Of course, they will never succeed because, if you recall, Utopia means “everywhere” and also “nowhere.” Communism is just a joke that has gotten ‘way out of hand.
