I suspect that since this is a noted Conservative forum that Jim has the right to delete non-conservative viewpoints and trolls. Free Republic is a specific website and trolls are generally given the heave-ho on all specific websites. Jim has never claimed to be a platform for anything other than Conservative thought and principles.
However, big tech DOES claim to be neutral when they are not and Prager proved it in court.
Again, why are you so afraid of making big tech follow the rules?
