Do you feel tortured? It would seem that you do. Why is that?
Yes, man does very evil things, is condemned for doing so, and is why Yeshua intervened to ask for them to be forgiven. That's also why His resurrection is so important, but sadly, Bibliophobes usually never get to that. They desperately look for something, anything they think they can use to discredit the Bible, ignoring the whole point. One may wonder why they are so evangelical about it. One knows, but some may wonder.
Would it be glorifying slavery to teach students about the experience American slaves went through? Your standard would seem to lead to that conclusion.
