The assignment was for students to do a presentation about the career of their dreams. As it happened, one of these high school students hopes to become a sexologist.
The teacher didn't require students to submit their dream careers to her for approval before the presentation. When the sexology presentation got underway, rather than censor the student, her teacher let her continue. Sexology is a legitimate dream, and nothing in the presentation was obscene.
Now, the Missouri honors teacher has been put on indefinite leave. What's wrong with this picture?
