You appear to have a stuck consideration that Texas will try to become the de facto 'boss' of the secessionist states. I don't know where you're getting that, but nothing could be further from the truth.
If you're so worried about it, stay behind and tough it out in the old union, or become an expat in some other country. You don't have to be our countryman if you don't want to. You've got all kinds of choices.
I think everybody assumes Texas will be the titular head since we’ve done it before... but not really as we have the most to lose, and the first to be attacked, because we’d be immediately successful.
