There is a guest commentary by Genie Scott at Real Climate:
Imagine you’re a middle-school science teacher, and you get to the section of the course where you’re to talk about climate change. You mention the “C” words, and two students walk out of the class.
Or you mention global warming and a hand shoots up.
“Mrs. Brown! My dad says global warming is a hoax!”
Or you come to school one morning and the principal wants to see you because a parent of one of your students has accused you of political bias because you taught what scientists agree about: that the Earth is getting warmer, and human actions have had an important role in this warming.
Something like this happened to me once. A student came to me after my lecture on Global Warming and told me his mother did not like my political bias. He also told me his mother was a state Senator and was going to do something about it. Not long after that Michele Bachmann introduced Academic Freedom legislation in the Minnesota Senate. So, I guess one could say that I started Bachmann on her illustrious career. Ooops.
Go ahead and read Genie’s commentary. Just in case.
