It'd be funny if one of the states was granted that, then the US would neglect the crossing of the US states to deliver goods to said state. Lets see how long till they ask to be let back in.
That whole portion of the United States is a useless money sucking pile of fat, misogynistic, and racist people. Whole area is useless aside from the major ports in Texas and Louisiana. Let them secede.
It would be amusing to watch them secede, realise just how much they suck on their own and then go crawling back.
I would feel very sorry for children who live there though and have no say in any of this and yet would suffer at the hands of the kind of government that a place like Texas would end up with.
Science in school? No way! It'll just get in the way of praying and bullying gay kids.
Homo***uals? No way! Off with you, to the electric chair!
Healthcare for poorer people? No way! You just die in a gutter you filthy poor person you.
You can't afford to raise a child and yet you're pregnant thanks to a date rape so you want an abortion? No way! You marry your rapist and be thankful to Jesus for the gift of life you slut!
A sensible look at how policies work based on reasoned discussion between people who are of sound enough mind to do the job? No way! All we need to know is what it says in the Bible!
