The conservatives took over the school board and decided they wouldn't use AP because it wasn't patriotic and would hire someone to write the curriculum.
The students went out on strike complaining they wanted to get advanced placement.
I'm not sure what came of that.
I can believe that. You can't rewrite chemistry to give a helium atom five protons instead of the two it actually has. But you can sure rewrite history. It's easy. Just throw in all sorts of personal slants. When it comes to AP History, I'll bet the conservative objections have merit.
