Exactly. This is why you can't have an honest conversation about gun control without discussing race. The second amendment is meant to allow citizens to protect themselves with firearms against the state. The framers of the constitution were extremely clear about this in their writings. What's the most famous group to do this? The Black Panther Party. Ironically, when the BPP exercised their second amendment right to protect themselves from oppressive state violence in the form of police brutality, conservatives like Ronald Fucking Reagan went on a mad dash to write new gun control laws. That's how modern gun control laws first got on the books.
Historically, U.S. gun control has its birth just after the Civil War, during reconstruction. However, the laws only applied to the millions of emancipated black Americans. Southern whites were terrified that former slaves were going to come and get revenge. Of course, blacks never did, but that didn't stop southern white militias from acting on their fears and using their guns to massacre black citizens. The entire purpose of gun control legislation then, and now, is to limit the right of blacks to carry firearms. That's why urban areas with high concentrations of black and brown people have the strictest gun control laws - verging on outright bans.
So to address the original contradiction. The pro-second amendment activists we see today aren't particularly concerned with state tyranny. Rather, their actions are motivated by centuries old racial fears. That's why when we see actual state tyranny in the form of white police officers killing unarmed black men, second amendment activists remain conspicuously silent. The police today are simply fulfilling the role of southern white militias during reconstruction.
I'm glad you know what you're talking about. Had no idea about this until I took a ethnicities and something or other class. It was excellent.
