Later on in Dred Scott the Court confirmed the common belief ~ to wit: slaves had no rights.
That is a RESTRICTION ON RIGHTS
So what class of citizens does that still apply to?
Is it just weekends or winter and nothing better to do, is FR getting kookier?
There were and are many restrictions on many people that are voilating the Constitution. Even though some Rights are generally not violated by government to one degree or another, as a citizen there is also a responsibility for one to stand up for their own Constutional rights.
These little “stories” about “slaves no gun rights or slaves not allowed to stop by a gunsmith” has nothing to do with their rights being Constitutionally denied. Maybe there was some “law” implied or enforced toward such, but that is a far cry from being Constitutional or unConstitutional.
It really assists in a worthwhile discussion to insure you are well informed otherwise it becomes for your own purposes only.
