[curiosity]

Very interesting. I went to the webpage, and tried to follow the link to the review of middle school physical science texts. Unfortunately it was broken. Do you know where else I could get that report? I'd really like to look at it.

Have you seen it? Does it provide any evidence that the errors it uncovers are deliberate and/or politically motivated?

That there are errors doesn't surprise me. That they would be politically motivated and deliberate I would find shocking.

I have not seen the report. I'm inclined to accept it though from other things I've read. If you are serious wanting to see it here's the contact page

Here's a Weekly Standard article that address errors, and P.C., in science textbooks.
