While we're talking about Texas being stupid, did you know handguns in Texas are illegal but unconcealed long-arms aren't?
What the forget are you talking about? I'm buying a handgun in December. Literally anyone can do it.
I'm also getting my CHL but I can open carry as well. At least put some effort into your handicapped baseless claims before you even try.
Also the state of Texas isn't making these textbooks afaik. If any blame is to be saddled it's with the textbook companies and their lobbyists that pay huge sums of money to let this stuff slide

"One civics textbook explained that segregated schools for whites and blacks in the Jim Crow era “sometimes had similar buildings, buses and teachers” – and only “sometimes” were the black schools “lower in quality.”" This is true up until high-level education. Segregated colleges WERE inferior in quality.
Also McGraw-Hill is loving RENOWNED for the stuff quality of their textbooks. The only reason people buy them is because they've been subsidized to the point that they're actually within the budget constraints of the school.
