There have been some recent studies that show a causative effect between entertainment violence and violent behavior. 85 posted at least one in the previous discussion that we had. So I think it would be prudent to not simply dismiss it as BS but consider it as a potential factor.Many of the discussions about social issues are also just made up BS trying to blame it on things like violent video games and Hollywood and what not. And, if we want to talk about mental health I think that is legitimate, but then we also have to talk about healthcare which I don't think is a topic many on the right would like to travel down. Mental health treatment is a part of healthcare. If we want to talk about homes without a father or parenting in general, I think that is legitimate too, but we cant talk about that without talking about how many of these fathers are locked up for non violent crimes. So I agree there are deeper issues than just guns (though the volume of guns in this country is absolutely part of this), but a lot of people who want to talk about other things on the surface without actually having solutions for those things either.
One parent homes are also a factor to explore, as you mentioned. It would be an interesting to look at actual statistics of how many one-parent homes are created by incarceration versus simple out-of-wedlock pregnancies. Not to mention the bigger question of how we penalize people for crimes. As far as violent vs nonviolent crimes, it is a very strange position that has emerged that people should only face punishment in this day and age for violent crimes. Non-violent crimes have societal impact as well, some far more devastating to people than any simple assault.
I would put forth that the volume of guns has no effect on this conversation whatsoever. The vast majority of guns and gun owners are never used in a crime and never put in a situation to be used for a crime. The issue is the possession of guns by someone with the malicious intent to do harm to another. It takes those two factors to cause the situation. Which brings us back around to the beginning where we need to tackle both issues. We need to tackle the first in a way that does not infringe on the rights of that vast majority of gun owners who responsibly keep guns and never have and never will commit a crime with those weapons. We also need to tackle the second in a way that does not infringe on the rights of the accused to due process and liberty. Red flag laws are a decent concept but the application of them needs to have the measured due process required by the Constitution.
