Hmmmm. If you can't pass a simple test...then you should not be allowed to vote.
Q. How many members of Congress?
Q. Name them.
That sort of nonsense went away with the voting rights act. Like it or not, the 2A protects a fundamental, individual civil R-I-G-H-T. One does not have to pass a test or demonstrate a need, or even justify why to exercise that R-I-G-H-T.
A CIVIL RIGHT dilineated in the BILL OF RIGHTS is not a heavily-regulated government privilege.
Nobody's advocating giving guns to crazy people or violent criminals with a demonstrated penchant for mayhem. But don't penalize the population for the acts of a relative handful of people.
Well stated as usual Dave.
