I wrote about this (teacher's name was Jerry Buell) previously.
My position was that the board has over stepped the line when a private face book post was the reason for suspension. I also posited that no one should bring his/her private belief into a classroom. Friendly Atheist got hold of a syllabus from Buell. Man, he should be banned from any teaching at any school for as long as he still subjects his students to his private belief.
