benstt,
Many, many women suffer post-partum depression. I can tell you of an Orange County, CA woman who suffered severe post-partum depression. She intentionally ran over and killed her baby. Using your logic, should moms with newborn babies have their cars seized because of only one incident of which I'm aware?
By definition, all murderers are either psychopaths or sociopaths. Mental illness is not a defense to a crime. Insanity is, but it's extremely rare. The Policeman's Rule (insanity defense) is a difficult burden to overcome.
I'm an unabashed Founding Fathers conservative. The neocon co-opted Republican Party left me a long time ago. Mitch McConnell, who obviously hasn't been cured of TDS, has told Republican senators to accept results of a rigged election. Neocons want Trump gone more than Democrats.
benstt, here's a definitive example of politicians ulterior motives. In CA, decades ago a five-day waiting period (AKA: "cooling off" period) was foisted upon We the People of the totalitarian state of CA. It applied to only handguns. That waiting period was extended to twenty days, which was a hard sell, so it was scaled back to ten days. Then long guns were included within CA's waiting period. Think about how draconian that law is. If I have 10k invested in a Rocky Mountain big game hunt, and a week before opening day, my rifle were stolen, I could not legally possess another prior to my hunt. In CA, it's a felony to loan a firearm to anyone but immediate family members.
CA legislated a one-handgun-purchase-a-month law. Now long guns will be included within that oppressive and unconstitutional law.
A mentally infirm exclusion of Amendment II rights would begin with an easy sell: criminally insane. Eventually it would include post-partum depression, followed by your neighbors' statements that they saw you exhibiting strange behavior.
What about a mentally infirm episode in a person's life? I can't tell you of how many women I know who were so devastated by divorce that inpatient psych care was discussed. One such woman is now an honorably retired cop. I know of a woman who was admitted for inpatient psych treatment due to her devastating divorce. That was 20 years ago. She can never possess a firearm because she was an inpatient psych patient. Is that fair? She's a danger to no one. Yet because 20 years ago, divorce stress resulted in inpatient psych treatment, she can never own a firearm. What about an alcoholic who cleaned himself up 30 years ago at an inpatient facility and hasn't touched a drop since? Do you really want to deny him ability to shoot a round of trap?
If you know the end game, and it's not destruction of Amendment II, that's an impediment to the end game, you can predict plausible actions of America's fifth column. The end game is the New World Order, or globalism, or one-world-government, or super government: they're synonymous terms. By definition, the end game includes destruction of the United States of America as she was created by shed blood of our Founding Fathers.
Be very careful of what you wish for because you'll likely get it...and regret it.
