Zedd has failed to acknowledge that the offensive usage of “Jew” didn’t originate with Erdosain. Bartman points out that the annoying little brother Nephi refers to himself as a Jew. So according to the Book of Mormon, the Book of Mormon is a story about Jews.
If using the word “Jew” to describe Israelites in inherently antisemetic, then the author of 2 Nephi is antisemetic and Erdosain is merely quoting him.
