This is actually the main policy stance of the Liberal Gun Club. That we're spending all this time regulating guns and ignoring/underaddressing the root causes like mental health issues, domestic violence, toxic masculinity, income inequality, poverty, etc.
Not to say that guns shouldn't be regulated to some extent, but with the way mental health is in America I'm pretty sure we'd just see a spike in knife and baseball bat crime and suicide by hanging if we somehow magically got rid of guns.
