Sure, why not have background checks for speech, assembly, redress, and practicing religion while we are at it.
Amen. How about a "universal background check" on everyone crossing the border?
This is all, entirely, what the Russians call "spectacle."
It is a presumption of status, subordination of citizens to the state, it is allowing a licensing by a distant power of the natural right to self-defense.
Where is the clear and present danger, even a "compelling state interest" in allowing a grandstanding Congress and federal bureaucrats and federal police superseding local regulation?
This is still allowing liberals and messed up liberal state governments and media monsters to frame the debate.
No quarter to the bastards. It's still "spinach," and I still say to hell with it.
