I see your use of the word "Ranger." Surely, if you've completed all phases of that training, you would understand the importance of training. Banging your head against the wall of truth is one way to wake up.I know it's pointless to bang my head against this wall, but what the hell.
I'm not ignoring a problem. I am actively looking for evidence of it, and not finding it. You are asserting there is, or will be, a problem without citing evidence of it. I don't "fear the solution might be used to infringe 2A rights." I have already observed that it does: long waiting lists for training; high financial burdens; long travel distances for multiple days. If these are not infringements, what could be? All for the promise of a benefit which can't be demonstrated, only assumed.
Your presumption of risk to the public applies equally to me. I assume that risk for the sake of others' liberty, not just my own. If that's your idea of "selfish," I suggest you consult a dictionary.
