Mental health is too open to interpretation to be the basis of determining someone's individual rights.
I took a stress test a while back in which you were to tick off items from a list if they'd happened to you within the previous 12 months.
Divorce, check. Immediate family member undergoing surgery or other serious health issue, check. Child reaching legal age and moving out, check times 3. Death of a pet, check. Household move, check. Loss of job, check. There were more. At the end, weight is applied to each item and you're given a score. A score of 300 was considered extremely high stress, even health endangering. My score was 900. What if they had used that to determine my ability to purchase a gun? Yeah, I was stressed, not sleeping well, fighting depression tooth and nail, but at no time did I ever contemplate suicide or homicide, nor would I ever. And you know if they decide to do mental health checks, some sociopaths are going to breeze right through it, but worse than that, who knows what cracked philosophy they'd use to make the determination - it's not like we'd have any say at all in the matter.
As to the AK47s, what an idiot. I swear not a day goes by when I don't think one headline or another is like a scene from a really stupid movie.
I saw a post on facebook the other day for one of the libertarian pages. I'm going to flub the words a bit so they don't attract search engines or enigma.
Support our troupes. We'll need them to over. thro. are. guv. Laughed my arse off.
