A sad state of affairs where propaganda by Hitler is being excused with "free speech".
Tell me one thing, Snestorm. When free speech is used to spread that kind of propaganda, and the propaganda is successful and a sufficient ammount of the population follows it again like it already once did, and thus the people revolt in a coup or by democratic elections overthrow the democratic order in a Germany that your grandfather's' generation have fought and maybe died for in order to establish it and to overthrow that Nazi regime back then, and germany again would become a Nazi tyranny today and demands Lebensraum and Arien superiority and we attack France and Poland again and have KZs, and in the following years again some dozen of million people find death because of us having had free speech and thus: nazi-tyranny and antisemtic progromes again while at the same time we have shut down free speech to protect our newly won Nazi tyranny from criticism and opposition -
would that be okay for you? 
After all, these things would have become strong again - because you willed them the space and opportunity to grow strong again.
