While I think Hawkmoon probably has it right, I like the second amendment sanctuary movement regardless because it shows political resistance to a movement that, while perhaps legally impotent, or questionable, shows wannabe tyrants like Gov. "Blackface" Northam that the people are not just going to roll over.
And if Hawkmoon were to suggest that the pro-2A movement cobble up something with actual, real, legal teeth, I'd agree!
