Not everyone in Texas is ignorant enough to take text books at face value and believe everything that schools spoonfeed! I'm from Texas and I'm quite liberal, well edumacated and planning a permaculture site between Houston and Dallas. Hopefully we can save some other Texans...
It's Ironic that I'm going to ask for censorship, but this is kind of a political topic, and I posted it before I knew the no politics rule, so I'm going to report it to a moderator and let them delete it if they want to.
History should normally not be re-written; it is usually plain wrong. That is, if it was recorded truthfully and factually in the first place, it should be left alone, studied and lessons learned from it. It can sometimes get a little fuzzy, for example, when histories of battles and wars get written. Those are usually written by the victors and will likely present the facts from the victors point of view. So there may be a 'skew' to that history. Sometimes it takes the passage of 50 years to learn all (most) of the facts.
We homeschool but will also tell you to go through the books from time to time. I found once section dealing with slavery that was very slanted against America, but not the Africans that sold their brothers, or Europeans. Nor did it mention the history of slavery throughout man's existance.
Bottom line, you are responsible for your children. Don't ship them off to public daycare and expect them to come back home with a love of their country.
HIS-story ( history) is always written by those in charge and written to make themsleves look good and to their own ends. It is up to us to dig further to find other views of whatever may ( or may not) have happend. PS.When I was in school ( a LONG time ago) the books said that the slaves were happy singing in the fields and slave owners were kind and loving towards them! The Native Americans ( Indians at that time) were blood thirsty heathens who all deserved to be killed. ( And furthermore the government set up and did a good job of trying to do just that!)...hmmm that last fact seems to have been "forgotten" lately.
I don't know about your public school experience, but I was exposed to a ton of revisionist history and outright brainwashing. That was in Los Angeles in the early 1960s.
Early on, I was taught that Indians and Pilgrims were pals and had a great potluck at the first Thanksgiving, and that the commies (Cubans and Russians) were going to annihilate us any day with nuclear weapons. We were all made to crawl under our desks and curl up in a fetal ball on a weekly basis as practice for the nuclear attack. Now, that tactic has dubious value in protecting from a nuclear blast, but it's a great way to program small children to fear and hate. We were taught plenty of other stuff too that I found out many years later was less than factual, and were never educated about some critical issues, but I won't belabor the point.
The point being that public education curricula, particularly the history and social studies components, often are designed not to make children well informed critical thinkers so much as easily manipulable, useful tools.
The Texas curriculum in my view is not an exception to the rule so much as an acute exacerbation of the pre-existing condition.
