I'm glad to hear this, because one thing I'm struggling with is the lack of conversation. My immediate social circle runs the spectrum on this topic, and it seems to me like so many people can't bear to acknowledge the complexity of the topic and run for their safe little corner, whichever one that might be. I have pro-gun friends who won't engage with the topic of meaningful controls on purchasing, and I have anti-gun friends who won't engage with the topic of civil responsibility and the risks posed by surrendering legally owned weapons. This lack of engagement and polarization is what scares me the most, and not only on this topic. It makes good governance impossible or at least unlikely.
I own and shoot guns regularly. If they could all disappear, I'd be all for it. But that option doesn't exist.
I think raising the age to purchase weapons is the wrong approach, for one because shooting with kids is so important to so many friends of mine, and for another, the kids I know who are the most involved with guns seem to be the least likely to misuse them.
To me, the right answer is a mix of many things. Helping young people feel part of their community, limiting exposure to glamorized violence, changing how these events are reported to take away the allure of becoming instantly infamous, and limiting availability of high capacity magazines all seem realistic. Mandatory training and licensure seem potentially appropriate, although the training I have been through to get a CCW seemed like a greater harm than good.
Past attempts at "assault weapons bans" have been so flawed as to be laughable, and beginning a meaningful registration program when so many guns are in circulation seems like too little, too late.
About all I am absolutely sure of is that it is a complex question and that anyone who proposes a simple answer, hasn't looked at the question hard enough.
