The History Standards mess of the Nineties really scarred a lot of people to the point where trust in centralized standards passed down from on high is a red flag.
I'd like to think that this time it's different, but it's hard to hear "I'm from the government and I'm here to help" without getting very anxious.
I understand that, but if it happens at the state level or the federal level, it's going to feel about the same. I know we cherish states rights because theoretically, we can move to the state that suits us, but really, most people don't have the wherewithal to move to Texas because their 3rd graders had to read "Heather Has Two Mommies."
