Consider why the jews have been kicked out of 300 different areas in the world over the past few thousand years. What is it that makes everyone hate them. I'm sure you have an answer to share with the class, given how silly the whole thing is. There surely must be a simple and entirely rational answer.
At what point do you stop holding the past against an entire people? Is forever your answer?
Do you WANT another holocaust? Because if there is something about jews that makes them objectively detestable and we don't find out what it is, then that is exactly what will happen.
