I completely disagree with you. The 2nd Amendment forestalls many arguments about what the law IS. It does not forestall arguments about what the law SHOULD BE. And it is important that we engage in a discussion about what the law ought to be. For instance, although courts do not (well, ought not) respond to public opinion, there is a public discussion going on now about the appropriateness of the government ordering Apple to rewrite their OS to allow the FBI to decrypt a phone. That discussion is healthy, and a good thing. As another example, I often engage with people in discussions of why freedom-of-expression (1st Amendment) is so important, and I am prepared to lay out the arguments for why it is a good law. The 2nd Amendment ought to be treated the same way. Those who think it is good policy should be able, and willing, to lay out the reasons why it is a good law. And many of them do. I believe some of those reasons may be based on bad science (e.g. "It is good not to restrict gun ownership because greater gun ownership reduces crime."), and we can talk about that. Other gun rights supporters pass laws requiring that no federal money be spent on collecting data on gun-related risks (perhaps for fear that the results will not support their positions?). I object to that behavior, and I hope you would too.
