I would rather be one of 10,000 random Texans with guns than 1,000 national guard.
10:1 are horrible odds in an urban environment against well resourced, well equipped, intelligent insurgents.
Houston for instance is full of chemical engineers, tradesmen, software engineers, and all around handy outdoorsy people. You clearly have no concept of how hard it would be to occupy and hold such a place against such an enemy. I tried to hold territory in Baghdad amongst people who couldn't even shoot straight and we were regular army not weekend warriors and it sucked. It was unpredictable and constantly dangerous.
Nope.
