I would say:
“If a law is unjust, a man is not only right to disobey it, he is obligated to do so.” - Thomas Jefferson
But we are way past that. If you register you put a big target on your back. If you register they will change what is allowed and come for your gun. Canada, Australia, New York city... They do it ALL the time. Registration leads to confiscation, each and every time. Always
We must recognize that registering guns is of itself an act of tyranny.
