Refusing to comply with Federal mandates which local areas believe to be wrong is as old as the U.S. Some say that the leftists "Sanctuary Cities" is a prime example. Nevertheless, the Whisky Rebellion is a good place to start but I think a better example is how most place in the North told the southern Democrats that they could take their Fugitive Slave Act and shove it where the sun don't shine.
That said, I do find it amusing how those people who sing the praises of the Sanctuary City movement bang on about how the Second Amendment Sanctuaries movement is so very wrong because it's defying the FedGov. What's good for the goose and all...
I also find it amusing that so many of the people who were decrying the Sanctuary City movement are now balls-to-the-wall for the Second Amendment Sanctuary movement.
Humanity would be fine if it wasn't full of humans.
Peace favor your sword,
