A coffee discussion would indeed be nice. Unfortunately, I can't think of a way to do so without exposing personal contact info (although Equifax or Sonic may have already done it for us) or inviting everyone who reads the Denver Post comments section.
Point 2): My memory is that there was a proposal to relax the conceal-carry law -- or introduce one. Then Columbine happened, and the Republican leadership thought passing the proposal "had bad optics", to use a horrid modern term. But, eventually, the next year's session maybe, the proposal was indeed passed.
Obviously, I agree with 5), but all too often, law is reactive, and if such a ban were to take place, between the length of time it would take to pass a bill and the law's effective date, anybody who wanted to buy a bump stock or trigger crank device would have done so.
You make a good point on 6). It is indeed complex.
Thank you for your feedback.
