The south seceded because they were afraid their property was going to be taken away.
This wasn’t about guns, it certainly wasn’t about land or anything else, it was about PEOPLE. You can’t deny that. The very proclamations issued by the states of the CSA are all over it.
And then, they fired the first shot.
You can screech about states rights as much as you want, but the concept has been warped to fit your very limited worldview while the slaves were still being held.
My ancestors, who were in the Army of NoVa, were from Bedford County VA. and none owned slaves. But even if they did it wouldn't matter. They killed a lot of Yankees, maybe some from Ohio. What difference does it make if the dead Lincoln storm trooper hero was killed by someone who owned slaves or not. A dead Yankee is a dead Yankee.
So if Texas secedes over air pollution regulations, then they are fighting to protect dirty air? You really are pathetic South hater. See a doctor, Prozac™ may help.
