It'll never happen. The Fed & many corporations wouldn't allow it to but for the sake of argument all those fake ass John Waynes in Texas would be face to face with Barbie n 'em shit would go from bad to totally fucked up.
Once the Federal government commandeers everything that belongs to them, which includes bases, weapons, border patrol etc., Texas would be Mexico again within 6 months, guaranteed.
Louisiana can't function now, what the fuck they gonna do as an independent nation? Same for Alabama, Georgia etc.
Pride has people believing they are superheroes but shit would implode shortly after secession took place.
Also isn't it ironic how these Southern states are the most patriotic flag waving states and are always threating secession? Lol
