Ok firstly, What is published on PhoenixMasonry's site is way off the mark with what the Authentic source site says.
"American Nativism* is a reported period in American history that continued well beyond 1845. Many acts that occurred during this era are shameful at best. It is important for the reader to understand that the Junior Order did not encourage or sponsor these acts.
It is known that a group of American citizens were responsible for grievous acts against Catholics and more specifically Irish Catholics in Philadelphia. One of the first known groups to grow out of the era was “The Know Nothings.” They were formed out of fear and it was a secret organization that continued to encourage defiant actions against individuals whom they believed were a threat to American liberty. Many things fueled those acts, but immigration and the resulting loss of jobs and income were touted as the main causes. Reading accounts of historical facts will provide additional insight to other causes.
American Nativist's held a general dislike and fear of the power of the Catholic Church and the resulting influence from the Vatican. While that is part of American history, it is not a part of the Junior Order"
