Not sure if anyone has seen this, it's a long read, but definitely a good one.
It is written by a licensed psychiatrist and digs pretty deep into why people are actually anti-gun, to understand not how they feel, but why they feel the way they do. It also dives a bit into how to show them the other side, how to diffuse a situation, etc. Unlike most pieces written either for or against, it actually includes references and historical fact to support the idea behind it. Enjoy (if you have the time)
