I'm glad my Biology teacher didn't skip it when I was in high school. Though I was a creationist at the time, his words were among the many that had an influence when I did finally recognize the fraud that is "Creation Science".

His first duty as a teacher should have been educating and inculcating in his young pupils a thirst for knowledge and truth. Any Biology teacher who would decide to skip the chapters on evolution should not be allowed to call himself a teacher never mind a science teacher!

Could he really have lost his pension over this or was this just some irrational fear?
