Should Schools teach about the "N" Word?

Can't even type the word in the context of an intelligent discussion. Sad.
Like closing your eyes when the truck is going to hit you.

Words are harmless. It is the thought attached to words that harms (or elates). No word has any meaning other than the thought we attach to it. "Discussing the word" is fruitless. It is the thought behind it that needs to be discussed.
