Based, I had a revelation on DXM one time that black Americans (i.e American Descendants of Slavery) have a stronger claim to being real Americans than Ellis Islandites like me. About the term? Like >>17932891 said, it was a popular anti-immigrant/pro-protestant reactionary movement in the mid 19th century. Gangs Of New York is a great film about them
