As RFK, Jr. pointed out, throughout history the censors have never been the good guys.
That is true. The problem is we find ourselves appearing to side with some really nasty individuals. Some Americans just cannot get over that hump that we must defend the right of free speech of the worst or we are not defending it at all. That means a person has a right to claim the Holocaust did not happen. And I have met such people and its not a great look.
