"text, history and tradition" is the only thing which will save the 2A. The levels of scrutiny (rational, intermediate, strict) were invented by the courts so that judges could uphold unconstitutional laws.
"In my view, Heller and McDonald leave little doubt that courts are to assess gun bans and regulations based on text, history, and tradition, not by a balancing test such as strict or intermediate scrutiny. To be sure, the Court never said something as succinct as "Courts should not apply strict or intermediate scrutiny but should instead look to text, history, and tradition to define the scope of the right and assess gun bans and regulations." But that is the clear message I take away from the Court's holdings and reasoning in the two cases." Heller v. District of Columbia ("Heller II), 670 F.3d 1244 at 1271 (2011) KAVANAUGH, Circuit Judge, dissenting.
