It's interesting that gun rights were sold on the basis of "resisting unlawful government." They seen to have caused and supported unlawful government.
Almost every tyrannical regime in the 20th century systematically disarmed their citizenry, leading to some of the greatest atrocities the world has ever seen. It's not a coincidence.
I guess "undesirables" don't count as part of the citizenry? You're only reinforcing my point, that the government stripped firearms from the people they wanted to kill/oppress. If it wasn't worth doing, nobody would have done it. Instead, Pol Pot, Hitler, Idi Amin, Stalin, Kim I'll Sung, Mao, Mussolini, etc., have ALL taken away firearms in some way from their peoples.
