Earlier quoted context omitted.
Well, the incorrect part of you analysis is implying that right leaning states would start the war here. Given the current state of upcoming election polls, local politics, and the supreme court, the right leaning states are going to get most of what they want. They have no reason to secede, when they are winning the current politics battles, and are likely to win future elections in the next few years.
The talk of secession is from the right leaning states. If, say, Texas were to secede, I wouldn’t be totally surprised if the US were to invade, after all that’s how the last civil war started. On the other hand, maybe they would do nothing.
There has been rhetoric from right leaning people, for decades on this,yes.
But the point is, that from the actual on the ground political reality, the right is winning.
They are winning in the courts, local/state power, and based on current voting polls, they are going to win in the upcoming federal elections.
There is no need to secede if you simply control all the levers of government. And the recent facts are that the right is only going to get more power.
Therefore, despite the rhetoric, right leaning places have no need to secede, when they can instead just take over the government the regular way.
