Except that it isn't true. Heck, even the state of Texas itself says it isn't true. Link
Texas is constrained by the Constitution in the same way and the same areas as every other state is. One of those constraints is that a state can't just walk out whenever they want to.
We will just have to disagree about that, SoJo.
There’s always one or more threads going on FR where posters cleverly and originally write, “Kick California out of the Union and build a wall around it!”
So here’s my question: could the U.S. really do that? I mean, I understand the Civil War settled the question of whether a state can leave of its own accord.
But what if all the states voted to give one the boot? Constitutional or not?
If or when force can no longer be applied, there is nothing stopping any state from leaving.
