That is not actually true historically. That is popular talking point.
On the other hand, quite a few authoritarian tyrannical movements started by arming themselves and taking it on themselves to get power. Both nazi and communists started as private citizens arming themselves and causing fights in the streets or robbing people.
"On Nov. 11, 1938, the German minister of the interior issued "Regulations Against Jews Possession of Weapons." Not only were Jews forbidden to own guns and ammunition, they couldn’t own "truncheons or stabbing weapons."
In addition to the restrictions, Ellerbrock said the Nazis had already been raiding Jewish homes and seizing weapons.
"The gun policy of the Nazis can hardly be compared to the democratic procedures of gun regulations by law," Ellerbrock told us. "It was a kind of special administrative practice (Sonderrecht), which treated people in different ways according to their political opinion or according to ‘racial identity’ in Nazi terms.""[0].
One example close from home, Belarus and Russian governments have gone to lengths in order to limit gun ownership. It is actually very difficult, at least legally. Perhaps when you are trying to stir a revolution you might speak to the nation arming itself. Once you have taken power, peacefully or otherwise, your next steps regarding gun control are still highly illuminating.
