Even if Texas seceded from the US, they will still drag the US down their "rabbit hole" due to lack of an organized counter balance on the influence their money has on text books.
Sadly, the open text book project won't be of much help. As great the potential of this project for increasing rational thought, ultimately, someone has to put in money to make the texts available, whether electronically or in print. The conservatives who are running text book selection in Texas aren't going to let federal tax money pay for it. And if they'd even touch it at all, more likely they would take the material, re-edit it, then make profits from the distribution (and maybe printing) charges.
The organizations still doing actual science are either under the control of similar conservatives or barely have enough money to do science, let alone donate enough to the open text book project to make a real difference.
And if a grass roots organization tried, how much money would it be allowed to raise before it gets either co-opted or shutdown?
