I used to be "sensibly" pro gun. As in, "it's important to give people that right, but with proper controls in place."
Increasingly, I want our country to have nothing to do with guns. The actual sensible position is very strict gun control. There's very little reason a person should own any firearm outside of a hunting rifle in extremely controlled circumstances with extensive checks and records.
The US has 120 guns per 100 people, the highest in the world. The next highest? Yemen at ~53.
The onion said it best (every time there's a new mass shooting), "No way to prevent this, says only nation where this regularly happens." We can't lie to ourselves that it's not the lack of gun control that allows all of these shootings.
If I could snap my fingers today and make all the guns in the US vanish, tomorrow we'd be talking about IED's.
I think the root problem is that americans have been squeezed to the brink and are losing their fuckin minds.
