Why should they be ashamed? Did they put those illustrations in there? Profiting (in this case with respect to good PR) off of others’ past mistakes is widely rewarded today, but it isn’t in any way morally correct.
There is no progression in society by dealing with past issues like this. I just hope more people realize that.
Yes, the illustrations were offensive. Yes, the books probably weren’t that great to begin with. But how we deal with it, how we respond to it, is just as important for our growth. That is the point I’m attempting to illustrate.
