JFK federalized the Alabama National Guard in 1963 to force the admittance of two black students to the University of Alabama (presumably a state school), and the federal government has been mandating “civil rights” ever since.
To say that the federal government doesn’t routinely smack around so-called “states rights” is ludicrous in the extreme.
The same principle should apply to guns. The second amendment is a right of US citizenship, not a right of residence in a state or city.
I know, I know, local gun control laws are in effect everywhere... but the point is, if civil rights can be enforced by the fedgov, then gun rights deserve to be too. Fair is fair.
Eisenhower sent the 101st Airborne to Little Rock to integrate the public schools there. States have no right to deprive citizens of their constitutional rights. The decisions of late wrt guns indicates a turn against the anti-gunners of dramatic consequence.
The second amendment does not mean that laws wrt firearms cannot be written and passed by the states and still be constitutional, they just cannot deprive the citizenry as a whole (or substantial portions) of the right to possess arms.
