You’re arguing until they fight they shouldn’t fight.
Direct action you take such as banning the EPA, seizing revenue en route, and other things is picking a direct fight that requires a lot of conflict. A CoS is a less aggressive way to get the result we need.
You want a fistfight in the middle of the street and until you get it you don’t support even giving the guy a mean look.
You want a guy punched square in the nose while CoS supporters
I’m arguing that when the states finally decide to stand up and fight, we actually still have potent tools short of a COS.
We should employ those tools, first.
The idea that a COS is the last straw and we are already there is flawed. There are plenty of options between here and there for states motivated to rein in the fedgov. Read the Federalist Papers. Our Founders were quite certain that the states would have an upper hand in battle with the fedgov. That’s how they designed the system to work.
