When I was in the convent, I met a lot of nuns who had been in other orders, but who were asked to leave simply because "they were too rigid" and "were holier than the Pope."
Maybe, but "Fr." Norton was dismissed not only from the Novus Ordo Redemptorist house but also from La Reja and some other unspecified (Traditional?) monastery and also didn't last with Fr. Pfeiffer. It sounds like there might be something else going on here.
