Yeah, people who are so fucked up that they can't even handle their own disability benefits, let alone carry a gun. They aren't even the issue. Obama's bill was going to transfer those 75k names from the SSA to the FBI to be blacklisted. Some disability rights and other liberal groups (ACLU) joined with the NRA urging Trump to repeal the bill because it pushes a stereotype that all mentally-ill people are violent. Regardless, no law will stop an angry kid from taking his dad's gun - that's a parenting issue.
Beyond that, our whole society is fucked anyways. It's cool to be gay, violence is glorified, you don't have to say the pledge of allegiance, God doesn't exist anymore, everybody gets a trophy.. all that shit has raised the tolerance bar so high that any little piece removed from a kid's Jenga tower can crash it all down. Kids don't know how to handle losing, nor how to work hard and appreciate winning since the losers are getting awards alongside them. There is no solution because none of that is going to change. Maybe if we send enough thoughts and prayers through facebook.. idk
