You can curb the frequency of mass shootings by making it harder for people to just stockpile guns and ammo. Destigmatize mental health and actually support mental health advocatcy, not just in emergency situations when someone has a break.
I get the appeal but there's no reason for people to have AR15s (know one wasn't used in this incident).
If you're not getting a handgun, shotgun, hunting rifle, you should have to jump through hoops to get your gun.
I grew up in the South. I get hunting, I get having a gun because police response times are slower. The fantasy of arming yourself against the government is gone. Miltias won't stop a thing, not in the way they think. I get owning cool looking guns, but get an airsoft gun if youre into tactical porn.
No one wants to the one who is in charge of cultural change.
