A substitute teacher in Battle Creek, Michigan has been fired for using the word "vagina" in a middle school art class while discussing the work of Georgia O'Keefe. The school district says she was fired for other (non disclosed) violations of policy, but really... this is all about the word.
Our own little niece Sarah brought home a science assignment from school one day last fall, and I noticed one of the words in the printed copy had been blacked out. I asked Sarah about the redacted word, and she said the teacher hadn't noticed the paper had a "bad word" on it, so everyone had to black out the "bad word."
I looked more closely at the science assignment. The redacted word was blacked out just before the word "reproduction." I asked Sarah to tell me the word everyone had been told to black out, but she wouldn't say it. It was THAT horrible! I told her it would be okay, just this one time, but she still wouldn't utter the word.
Then I asked if the bad word in question might happen to be the word "sexual", and she nodded that it was indeed the "bad word".
If science teachers can't use the word "sexual" in context of a discussion of reproduction, and art teachers can't use the word "vagina", we're doomed to raise yet another generation of uptight, sexually repressed people who will probably freak out about things like gays and transgender people using public restrooms.
