You're going to use the number of Google hits for "texas textbooks" as evidence? Really?
No. He's going to use the millions of articles that Google finds as evidence. It's not the number, it's the contents.
For example, link #4 (on my view, at least, is a HuffPo article stating that "A far-right faction of the Texas State Board of Education succeeded Friday in injecting conservative ideals into social studies, history and economics lessons that will be taught to millions of students for the next decade.
Board member Cynthia Dunbar wants to change a standard having students study the impact of Enlightenment ideas on political revolutions from 1750 to the present. She wants to drop the reference to Enlightenment ideas (replacing with “the writings of”) and to Thomas Jefferson. She adds Thomas Aquinas and others. Jefferson’s ideas, she argues, were based on other political philosophers listed in the standards. We don’t buy her argument at all. Board member Bob Craig of Lubbock points out that the curriculum writers clearly wanted to students to study Enlightenment ideas and Jefferson. Could Dunbar’s problem be that Jefferson was a Deist? The board approves the amendment, taking Thomas Jefferson OUT of the world history standards."
So, we eliminate Jefferson (a Deist) and replace him with Aquinas (a Catholic theologian). In what way is this not a "right-wing pro-Christian bias"?
To continue from the HuffPo article, "Ultraconservatives wielded their power over hundreds of subjects this week, introducing and rejecting amendments on everything from the civil rights movement to global politics."
Hundreds of subjects this week.
Let me turn it around. Can you cite a single piece of actual evidence that the recent changes are anything other than a state mandate to teach with "a strong right-wing, revisionist, pro-Christianity, anti-science bias." If that's not what it is, what is it?
