You can be offended by slavery, but not by a story about it. This sort of mentality leads to book banning, then book burning, which in my opinion are not much different. That's like hospitals banning beds. That s like swimming pools banning water. Well, let me tell you something about anger.
Anger is a secondary emotion.
It does not and cannot exist by itself. It is derived either out of fear or pain. Book banning is the work of Nazis in disguise, and people who consider themselves educators of any sort should not tolerate it. Now, there are people who will disagree with me, just like I disagreed with the person who introduced me to the concept that anger is a secondary emotion. But stop and think about all the times you have been angry.
