I don't think enough people will ever get fed up, just due to the demographics of our state. Maybe enough to make it more of a talking point, but those serious enough about it to do something will likely remain on the fringes of our society. I don't see it ever becoming a mainstream movement.
I really don't think we could stop them. If they can't take it, they kill thousands of texan soldiers in the process of destroying it so that we can't use it against them. And considering a high number of members in the armed forces stationed in Texas aren't actually from Texas, we'd have a very hard time keeping it with the hypothetical enemy already stationed here.
