All the more reason why it needs to happen sooner rather than later. The gun nuts can hide behind the Constitution all they want, but at the end of the day, the prospect of armed goons dictating policy at gunpoint is a far bigger threat to our democracy than anything that gun owners think that they need to defend against. You can hardly claim to be a law abiding citizen if you are constantly threatening to shoot people if the laws get changed to something you don't like.
