The most major issue with this propaganda piece is that gun control was not responsible for the rampages of Hitler, Mao and Stalin. Extermination of peoples did not begin with new gun control legislation. No government ever went door to door, demanding weapons, and then shipping people off to camps immediately afterward. China and Russia always had autocratic regimes with very limited individual rights(look up The Emancipation of the Serfs), while Germany relaxed gun ownership laws in the period after the Weimar Rupublic.

Retarded paranoid fantasies like this just make legitimate responsible gun owners look like delusional kooks.
