What exactly does that have to do with math or intolerance?
IMO, Philip Zombardo's studies (most famously, the Stanford prison experiment[0]) suggest this is nothing new.
EDIT: To be fair though, it does have a Jewish connection - cattle trains?
I am, however, Jewish, and was originally a math major in college, so I do have a particular interest in this story and would appreciate it if the conversation could stay on topic.
The "cattle train" connection is pretty contrived. One is voluntary travel, the other involuntary. One is certainly a breech of dignity, rationality, and privacy, but the other was often deadly, and is at a completely different level of dehumanization.
