Boy I couldn't agree with you more on the textbooks.
Reminds me of a story where they were taking the picture of George Washington crossing the Deleware and EDITING it - because some passively perverted parents looked in their childrens' textbooks and decided that his dangling pocket watch looked like a penis.
Slanting the facts, the "perception" of what happened... and even editing famous paintings to fit someone's idea of what "should" be in there... arrrghh.
Any day now they'll say the Mona Lisa looks too unsure of herself and might cause prepubescent teens to question their self-esteem, so she needs to be edited...
