Prejudices

I think that it is strange that there are so many kinds of prejudices. there are the people who oppress the blacks in Africa, or the men who oppress women in Afghanistan. It's amazing that you can hate so many people. I do not even know why the Jewish race was punished in the holocaust. Seriously, what did they do wrong? I have no idea, but Hitler must have. You really wonder how many prejudices there are in the world....
