Americans, Americans of all people, with their recent KKK history and Latin American examples right in front of them, should know that it's not the government's army you have to watch out for, when a flip to authoritarian rule is in the balance. That's not how it happens.
Then we don't need firearms to defend ourselves against the Military or the Government, as 2A thumpers continually claim, and given that the US Military Oath is to the Constitution, not the Government, if the Government goes rogue then the Military will (should) take care of it.
So, the point still stands - if the US Military goes rogue, armed citizens are fucked. If the Government goes rogue, and the Military stands with them, armed citizens are fucked. If the Military does its job, then armed citizens are basically superfluous.
SO, that said, we can safely say that we do not, in fact, need lethal weapons to defend ourselves from a tyrannical government nor military, and they are, in fact, necessary to defend ourselves against other armed citizens who have broken the law (eg, slavery).
It would stand to reason, then, that we can lay that argument to rest as a defense against re-examining the role firearms play in everyday America.
THAT said, I think some discussion on what kind of common-sense changes can be made that would help prevent mass-shootings is in order. Would you agree? Or, would you prefer to do nothing and allow yet another school to be shot up...?
And yes, I'm a bit peeved by the hem-hawing that has been going on for years. Hell, the school districts my mother teaches at and the one my newborn is likely to attend in a few years (based on our location anyway) are both closed today because of what was deemed a "legitimate threat" made against them on social media. It's beyond ridiculous, and this apparent desire to do nothing useful and offer up "thoughts and prayers" every time this continues to happen is beyond pathetic.
