Most Likely to Secede

Why are Texans so obsessed with the idea that Texas is "the only state that can secede from the Union?" I don't get it. For one thing, it's dumb. Don't be ridiculous. We all know that every hardcore Texan has some sort of fantasy that if the War(you know which one I mean) suddenly broke out again, they could grab the nearest firearm and start shooting Yanks. But that's not going to happen, so stop being silly. And secondly, it isn't true. Vermont joined the United States upon the condition that it could leave at any time, as did other states, such as New York and Virginia. Furthermore, according to Texas v. White, even if every single person in Texas voted to secede, it wouldn't be legal. I'm pretty sure that after the Civil War, the federal government made sure that secession was no longer a legal option. So I don't know what people are going on about, it's all a rather large amount of ballyhoo over nothing. Texans are strange. Just get over it, y'all.

EDIT: This is actually kind of interesting. More than a few states, including Vermont, have current secession movements. Most of the websites for the Vermont movement cite a lot of pre-Civil War material, such as quotes from the Founding Fathers, the Constitution, things of that nature. But they conveniently seem to ignore the Supreme Court case I mentioned, which interprets secession as unconstitutional. I mean... if you can't do it, you can't do it. I'm not saying I don't think they're right in some respects, but it looks pretty rock-solid to me. It's illegal, no matter what Thomas Jefferson might have said.
