Can someone explain to me what the current events teacher should have been able to allow if not the Pros & Cons of the current conflict? Perhaps he should have disallowed World News and only have taught National News, no that would not have worked either, how about Local News, no there might be a local involved! Seems obvious to me that we just cannot educate the youth on current event because it might upset someone.
Hmmm, with that in mind we should not teach history either, someone is going to get pissed off about that as well.
Now in the English class this situation could have been solved in advance by the teacher giving the students a list of approved topics from which to choose.
Bottom line as long as they were the students thoughts and expressions, pro or con, I say let them stay. If they had been the teachers on the other hand, that would have been improper!
