"Guns are amazing"? Really? Nevermind, I know someone just like you. He refuses to fly on an airplane because he can't bring his precious guns with him on the plane. So he's really never been anywhere outside of the midwest. He has no idea how other countries are. And I've never felt safer than when I lived in Europe for several months, away from all the gun maniacs.
The combination of rampant mental illness and entitled assholes and guns in America is a toxic combination. School shootings and mass shootings are things that happen all too frequently in the US, and not too much anywhere else.
But I suppose you'll handwave away all of it, and everything, so you can continue to cherish your "Amazing guns" without ever considering that maybe even more guns is not better for us as a country.
That said, I do NOT endorse this ridiculous 3D printer bill that California is trying to pass. And not because it's about guns, but because it isn't necessary.
