You've been given far more than you fair share of breaks. What you fail to understand, or more so attempt to ignore, is how often you're caught trying to argue a point no one is making....in this case, that the 2nd amendment is all about overthrow. That has never been a realistic premice to the 2nd, only fodder for hard core leftiests to try and claim that's the issue, and thus demonstrated how flawed that tact is.
Seccession is not overthrow.
"Thinking twice" is the point that because the citizenry is armed, it won't be a nice simple rollover, if ever the notion came into an oppressive minded Government intent on "improving security"
So, one more time, the 2nd amendment isn't about overthrow Professor Wrong. That would only occur if the oppression effort was so over the top, the military would turn. But the left has learned that slow & methodical is the way to go....suppression of this here, regulation of that there, restriction of just this, and limitation of just that. All those little efforts, while the lunatic left cooks the frog in the slow-to-boil pot
