After careful consideration, I've come to the conclusion that we must get back to the very basics on this.
The NRA and other gun lobby organizations as well as their ardent supporters have a very simple and to date, effective strategy for dealing with any sparks of reform.
What they do is quickly snuff them out with lies and vilification, fear and intimidation. They might use one of those, or all of those too. The point being to very quickly marginalize efforts to have a rational conversation about gun policy, then turn the conversation to anything else, so long as it isn't rational with regard to gun policy.
What to do?
