In D.C. vs. Heller, all nine Supreme Court Justices agreed "there's a Second Amendment right to own a gun" (the so-called individual right, vs. the "collective right" that had been claimed for decades), they just split on if this meant anything (D.C.'s ban on new gun registrations was total, and they effectively banned the use of any grandfathered guns for self-defense).
It is now settled law, there's very little to have a "national discussion" or "conversation" about, especially since we all agree on minor details like: murder is wrong and is properly illegal, felons and the severely mentally ill have no right to own guns (although due to privacy issues it's very hard to do anything about the latter, and too many states like Pennsylvania refuse to report this to the feds), people should treat guns with respect, etc.
