I always found anti-Semitism puzzling, as Jesus himself was Jewish.
I've dealt with anti-Semitism on and off for much of my life.
On top of that, I'm part Native-American (my mother was related to the Lakota Oglala Suoix).
I get particularly irritated when people bring up the supposed "cheapness" of Jews, and how we're lacking in generosity.
In history, Jews were often denied the rights of owning land, so my father's people specialized in business and commerce over farming.
We were blamed for bubonic plague (the Black Death) in the middle ages, as Jews tend to stick to rules about cleanliness, and we don't tolerate rats and fleas all over the place (rodents are specifically mentioned as being "unclean" in Leviticus . . . and they are).
This meant that Jews were often spared the ravages of plague, while the gentiles surrounding them died off like flies. This led to pogroms, accusations of witchcraft, and so forth.
Jews had to be preppers . . . which meant carrying portable wealth (like gold, diamonds, and jewelery) when resettling somewhere else.
