I visited Texas. I read of the events and the struggle there to remove the yoke of Mexican oppression imposed by the dictator Santa Anna. I went to the various sites where important events occurred. I saw the places where ad hoc groups assembled to provide a semblance of new government.
Sam Houston came along and became the force around which all the disparate groups and individuals could and did unite. They prevailed by force of arms at San Jacinto but mostly by force of pure old will. The desire to prevail, to win, to make change was the motivator for success.
I would offer the Texas war of separation as the example to follow. Sam Houston must be found. San Jacinto must be fought.
We must all become Texans
Did you forget that the Battle of San Jacinto (1836) was fought by about 1,000 troops on each side, and a total of three old cannons between them?
The battle lasted all of 18 minutes, and cost the Texas only nine killed.
Victory was quickly won by surprise and courage against a relaxed unprepared enemy.
But any thought of future victories so quick and simple should have been erased by the four years and 600,000 deaths in the Civil War of 1861 - 65.
Bottom line: you are never going to fight your way out of the United States.
Yes, you might lawfully secede, but that would require mutual consent of the other states, which means many years of patient, persistent & frustrating legal efforts.
And if you did ever actually accumulate such political voting power, wouldn't it be a lot simpler just to change those laws you don't like?
