The immortal contribution of the American Declaration of Independence is to recognize the existing reality that our rights are unalienable. At least they not a subject to being aliened by others, whether Kings, tyrants, or Democrat administrations. One can presumably knowingly and willingly surrender his rights but nature's God ordains that they are otherwise unalienable.
If someone is so clinically crazy that he cannot be countenance to have a firearm, he does not have a right to a firearm in the first place. Neither the Founding Fathers, John Locke, the authors of the Constitution, nor the authors of the British Bill of Rights considered that a maniac had a right to a firearm. But that is a different matter from taking the right away from someone who is mentally competent and who is possessed of an unalienable right.
Finally, someone suffering from a depression may not through her propaganda project her own neuroses on the whole society to deprive it of its unalienable rights.
