Is that a society we want?
Don't we have to work with what we have, instead of what we wish we had?
Any society is going to be defined by its people, and people largely suck. There is no democratic movement from where we are, to where we would like to be. Much as we can campaign for it, there is a counter campaign to keep things as they are. Yes, mass shootings all over the place is terrible, but people cling to their guns as their way to escape the next gunman. The statistical fact that allowing everyone to be a gunman is going to cost more lives, that is too complex an idea to overcome the simpler idea of arming yourself.
Part of the strength of their argument is in saying you can only disarm the "good guys" who would defend themselves, and they pretend that we could never disarm the criminals / murderers. That we only intend to make people more vulnerable. And certainly, anyone who is not armed has got to feel more vulnerable in America. Our campaign has to overcome those feelings and pound home the idea that other nations do not have these problems. People need to understand, they need to FEEL, that a solution is possible.
All people inherently understand is that the solution to a gun... is a gun. It is extremely difficult to move past that simple concept.
What if you are a teacher? History shows us 6 year olds in this country have access to guns and can kill you. What is the plan to kill all your 1st grade students?
Speaking of which... they'd obviously tell you to be armed, to be trained and competent. To be "ready". AKA itchy trigger finger. Let's just hope the 1st grader doesn't sneeze unexpectedly.
