If you can’t understand why guns are used in the US then why the hell are you even commenting about it? Do you just like to argue for the sake of arguing? You already admitted your uninformed, so why should your uninformed opinion carry any weight?
I’m also gonna head you off and say that yes, the US (and the world in general) does have a violence problem, but outlawing shit never works. Prohibition didn’t work, the war on drugs didn’t work, and the war on terror is a huge fucking failure. What makes you think banning “killing machines” will stop anyone from murdering each other? This is a mental health and criminal issue and if the past has thought ya anything, a determined person can cause a lot of damage with just about anything.
