Federalism, ie the idea that independent states band together for their mutual benefit, to accomplish just the specific things that they cannot accomplish independently, ie common defense, trade without impediment, and the other 15 of the total 17 things specified in the Constitution that are the sole responsibilities of the federal, not national, government.
And beyond that, people are free to make their own decisions and vote on things that affect just themselves without imposing their will on others or having others will imposed on them. So if folks in California or more specifically San Fransisco want to live a particular way, no problem. That is their right. They get to do that. I don’t have to live under it or pay for the consequences of it. Likewise, if I want to live with like-minded folks in another state or locality and vote for and live under a different set of rules, I get to do that. No one is forced to stay in either place and support it or pay for it. They can move.
The alternative that the lilb-progs are trying to take our country towards, socialism, communism, or fascism, has a control by a central authority, theoretically “the will of the people” except it always ends up being a few chosen incestuous power-brokers, a new royalty, who impose their will on ” the little people”.
Fought a revolution to get away from that.
Willing to fight another one.
