While there are some legitimate points there, you aren't going to score points in the narrative by talking about how your middle ground was reached by giving up missiles and poison gas weapons back in 1934. That would be somewhat like telling a women fighting for equal pay that she should be satisfied that you gave up The Code of Hammurabi, which made it legal to beat up your wife children.
Let's set missiles, poison gas and hand grenades aside and just look at firearms.
For simplicity's sake let's say that there are 3 basic types of rifles. Automatic, semi-automatic and manually repeating (pump action / lever action / breech loading / single shot)
Fully automatic rifles have been heavily regulated for quite some time. Manually repeating rifles have, for the most part, not been overly regulated. Semi-automatic rifles are legal with some restrictions in place.
That, to me, is middle ground.
Continuing to push for more restrictive gun control laws, in the absence of any real effort to find alternative solutions, is a non-starter for me.
