Such rationales certainly cause thoughtful folks to reconsider the status given to tenure and academia in general, don't they?
I do not believe tenure is valuable to anyone - certainly not to the students who are STUCK with incompetence in a field of study where they need to know the best information in order to perform a job. It's actually frightening.
And .. if a teacher has accountability as part of their JOB - like the rest of us - perhaps they would be less likely to spew their Communist agenda in the classroom - where they could be removed for NOT TEACHING THE SUBJECT they were hired to teach.
