And as a related point, if there are strongly similar cases, do you have any suggestions for how to present the information to someone who thinks that today's bigotry is totally not like previous cases?
I don't know why this still doesn't have an answer. It's a really pertinent question, though maybe too "Gather citations to prove to the people who disagree with me I'm right and they're wrong" for a healthy debate.
Never mind previous cases, the "bigotry" against Arabs and Hispanics are of entirely different natures in the current case....
