I think you also have made an assumption about me, that I'm interested in polarization. Maybe at one time I was. I had been a disciple of the NRA for decades. I gave no quarter to anything that even smelled of "infringement" because me in my purity of ideology would not even consider any common sense gun measures. 

I've finally let pragmatism work its way into my thinking, and am willing to see that Australia actually accomplished something. They had numerous mass shootings before their legislation. They have had zero since. I am a Psych major very familiar with statistics and design of studies and how they can be manipulated. If you can show me another reason why Australian kids eating in the lunchroom have much less reason to fear being shot I'm all ears. Until I see reason, I will continue to counter the unreasonable and inaccurate rhetoric of the NRA. 

My best to you.
