You are putting words in John Galt's mouth. I don't believe he said, or even implied any of those things.
There is a difference in restricting the rights of one who has proven himself a violater, and restricting the rights of a law abiding citizen. Restricting the rights of a person who, according to some nebulous governmental entity, just might be a threat is very different from restricting the rights of one who has proven such.
Noooo, I am not putting words in anyone's mouth - I am asking questions and taking his statements to the next logical step. He unequivocally stated that when "mere mortals become the adjudicator of who can have what rights, they are no longer rights, but privileges" which certainly sounds like an argument that "mere mortals" should NEVER be able to restrict the rights of anyone. I was and am questioning if that is what he meant.
I agree completely that someone who has committed a crime is different from someone who has "only" been judged to be a danger to themselves or others. But here's a hypothetical for you. Here in Washington State, if a child molester or a rapist has served their sentence, but the prison mental health professionals evaluate them and determine they are still a risk to re-offend, they can continue to be incarcerated indefinitely.
Right or wrong? Should they be released to prey on other women or children - even though they have done their time for the crimes they have committed? Or should we be able to continue to keep them locked up based on the assessment of their probability to re-offend made by mental health professionals? If you say we should let them go, are you OK with them moving in next door to you?
And if those same mental health professionals say someone is a danger to themselves or others, do you still feel they should still be allowed to exercise their gun rights without having to prove they aren't a danger? I'm as pro 2nd amendment as anyone, I've written numerous papers on the subject.
However, I'm starting to come to the belief that there are cases where rights can justifiably be subject to restrictions, when a person is unable to exercise them responsibly, and therefore endangers or infringes on the rights of others. And that applies to 2nd amendment rights too.
Should the suspension of a person's second amendment rights be something easily accomplished on the word of just one mental health professional? No, I don't think so. Should such a suspension be easily reversible if a person can present evidence of their mental competency? Yes, I believe so. But I do not think we should have to wait to do something about someone like the nutbar in NC who shot and killed 9 people either - especially when his predisposition to do so was well documented.
Just like shouting FIRE in a crowded theater isn't protected freedom of speech, and my freedom to swing my fist ends at the tip of your nose.
