Have you ever seen anyone arguing against mental health help? Only one of the two solutions you mentioned has a bunch of idiot fighting against it.
You also can't make mental health illegal overnight. People are born with mental health issues, it's not something they buy at the store or grab from their fathers closet.
Ban guns, ban guns now. Fuck gun culture and fuck all gun owners (even the responsible ones)
I understand your point, but everytime I see someone pointing at mental issues, it just seems to be like they will point at anything except the guns. We can thoroughly take care of the more complicated part of the problem once the easy part has been solved and they are killing childrens with knives instead of bullets.
The access isn't as easy at all. It's also the culture though. Nobody buys guns for fun or to show off, they aren't toys, there are barely any gun ranges and you don't bring your kid to it.
You maybe have a gun for hunting, it isn't an assault rifle and you only pull it out when you do go hunting.
