Interesting approach; one might ask about “ordinary sales taxes” but it’s kind of parallel to the way that religion is treated, or at least supposed to be treated. Churches get to make some transactions tax free.
I might suggest a skill or training requirement, in harmony with the “well regulated militia.” With that right comes a duty to make an effort to do it well, and the amendment even says so.
Agreed. (1) Pass a simple, basic national firearms standard course/test or (2) Be a military service veteran.
Check out all the green States at the end ... I do NOT want to go back to having to ask the State "Mother may I?" to exercise my right to bear arms.
I might not. Establishing a skill or training requirement means setting standards which are, most likely, enforced by whatever government entity the training program installs. With that in mind, think about how the standards can be abused, misapplied, or be unreasonably attainable. If you’re in doubt about this, recall the Southern states and their requirement that black voters “pass a test” before being granted the inalienable right to vote. Having a government arbitrarily decide who does and doesn’t qualify to express his inalienable right doesn’t work.
