I just know the guy would have called my communist grandfather and my anarchist father right wingers cause of differences in social values.
That sounds pretty humorous since
dictatorship of the proletariat isn't exactly a subtle part of Marxist philosophy.
The main critique of the anarchists against communism was that once a dictatorship of the proletariat was established, it would never progress beyond that stage. 100 years of red revolutions later hasn't proven the anarchists wrong yet on that front.
