If rural Virginia does not want to enforce the law, then they should receive no further funding from the state government.
Then they should stop paying taxes. No services, no tax. Come and collect the money from millions of angry citizens by force and see how it works out.
Good — let them go feral. Remember: they leech off of us, not the other way around. And if they want to organize a violent insurrection — which is exactly what you're threatening — they can confront the full force of a lavishly funded, technologically sophisticated attack. They'll be wiped out, just like their depraved Confederate brethren a century ago.
I am suggesting nonviolent resistance to unjust laws, you are the one advocating violence buddy. Yeah, I guess you could send tanks across the hills or use drones on fellow Americans risking a civil war or insubordination from soldiers who won't murder the people they are supposed to be protecting. Also, just ask the Viet Cong about lavishly funded, technologically sophisticated attacks. Some people say the second amendment is useless because the government has more tech, remember such a conflict would not be a conventional war like the Civil War was. To be 100% clear, I am not suggesting or hoping for a civil war, I'm just outlining how the violence you are advocating for would play out. I don't know who would win, but I know who would lose: our nation.
