I read quite a bit about this a few months ago when one of my friends on FB was shouting, "We won, we won." on her wall in regard to this issue. My favorite change in history is Phyllis Schafly, a well known anti-feminist, will now be the only person mentioned in the small section about the Women's movement.
The only thing that makes me feel better about any of this is that the majority of the ridiculous changes, like a big section about Gingrich's "Contract with America" will never be taught if Texas is anything like Louisiana since I can't remember a single year that my class got beyond WWII in history class!
