Comedian Joe Rogan tweeted on Jan. 27th of this year, "This country has a mental health problem disguised as a gun problem and a tyranny problem disguised as a security problem."
I agree. But that actually makes the problem much harder to deal with. Because what constitutes a mental illness is open to popular interpretation. There are plenty of people in the world willing to claim I have a mental illness (like this guy, this guy, and this guy). Requiring a clean bill of "mental health" before you are allowed to enjoy your Constitutional rights negates their inalienability. I do lots of things that are increasingly considered crazy, like praying, homeschooling, and believing in personal responsibility.
The day is coming (and is not far away) when insufficient support for the central government is considered a mental illness. "You're just paranoid! You're a sociopath! You're a narcissist!" And after all, do we really want guns in the hands of paranoid sociopath narcissists?
This is why I don't support stronger mental health requirements for gun ownership, even though I completely agree that America's biggest problem is a mental health problem.
