Here's what I think should happen in the realm of gun control.

39. those are the only two choices

the pendulum has been swinging DTR or SYG for the past 136 years. Both theories follow five principles

The hardest to define is reasonableness. What is reasonalbe in Wyoming and New York, both DTR, is different than Florida and California, both SYG. It varies between the states and federal level. For example in Florida, if the attacker backs off or retreats you can not continue or counter attack. I think that is true of most states other than California, where you can in some cases (yet they have a duty to retreat within the home.)
Like I said before, I think the problem is disinformation from DTR fans and laziness on the media's part.

I do think every state's CCW class should should explain those principles in detail as well as that state's statute or common law on the issue. That, and people who carry without knowing how to open the revolver's cylinder, is my biggest issue with "green" states.
