I use to be pro-gun, even though I'd never personally own one. Then I moved to Australia and later New Zealand. America's gun laws are absolutely fucking insane.
I think it's okay to own one, but everyone should have a license. None of this cash and carry bullshit. You have to register your car. You need a license for a car. If it wasn't for the 2nd amendment, no one would question license and registration for guns. Cops should have to register their guns too and should never be allowed to take service weapons home with them or use them off duty. They should need civilian licenses just like everyone else.
You know what goes down with sane gun laws? Suicides. Australia's suicide rate plummeted. Sure people who are going to kill themselves will usually do so no matter what. That's what you lean in psychology class. But they also don't want to fuck up. The only thing worse that surviving for someone that depressed, is surviving with permanent brain or physical injury. Guns provide that push over that edge; to assure you there is no recovery.
America's gun laws are insane compared to every other high income country. And Americans are oblivious to the fact it makes us the laughing stock of the entire world.
