re (1) then it's time to start standing up state laws that assert sovereignty, and legal supremacy over autocratic dictats from the out of control federal executive / judiciary.
re (3) yes, that's where we basically are. Red state (un)patriot militias hopped up on social media rah-rah juice about how they've been wronged, being sent into blue states and let loose to attack citizens. If our American ideal of Constitutionally-limited government is going to endure, then states need to start picking up the slack for the governance being overtly shirked by the federal anarcho-tyranny.
I don't like any of it and the dice are stacked against us, but the sooner we acknowledge the reality the better we can defend against the all-too-plausible possibility of our country going up the smokestacks of Trumpist big tech fascism.
