Having probably one of the few active people here that has actually been through the Texas education system, unlike the starter of this thread who doesn't even live in America, I can fully say that there is absolutely no set-guidance of Leftist Rightist teaching in any of our classes. Needless to say, the TBE can approve anything they want, but it divides down from State Approval, to Region Approval, to Cluster Approval and in the end individual school approval. They've done this before and it ended up being used in one or two schools. AHS, at the time I was there, had refused to teach something the TBE passed over something regarding politics.
You guys act like this is drawing black lines through our books and saying 'X NEVER HAPPENED' when in actuality it's just going to ask, not demand, teachers to teach more on the Republican-Focused bullshit that doesn't even matter.
Either way, read the last damn line. It was defeated because we're not all fuckups. People like this live in every state, every district, every fucking country.
