Think this an isolated event?
And it isn't just surveys. Many sex ed programs are graphic and offensive. Here's one in Shawnee, KS that teaches 13-year-olds about oral sex, anal sex, and other graphic sex terms. Think about children being exposed to this in the classroom with boys and girls present.
Texas is supposed to be so conservative, but the graphic programs are in Middle School there as well.
North Carolina's explicit program for 9th graders includes how to use lubricants!!
No surprise that San Francisco would have an offensive program, but vibrators and bondage? Talk about destroying the innocence of the young. I didn't know about that until I was a married woman with children.
