I do not believe that states should ignore federal gun laws that are constitutional. However, states have a moral obligation to ignore all unconstitutional federal laws, whether or not the Supreme Court steps up to overturn those unconstitutional laws. The people are the ultimate source of government power and thus the ultimate authority on when the government has overstepped its bounds, even if the Court fails in its duty.
“I do not believe that states should ignore federal gun laws that are constitutional.”
Do you mean laws that are constitutional? Or laws that the Supreme Court has ruled are constitutional?
There’s a big difference. The Constitution does not say that Supreme Court rulings on constitutionality are final. In fact, most of the founders regarded state decision as to constitutionality in this regard as an important check on the power of the feds.
