Thank you for the detailed answer. I hope my question didn't come across disrespectful. I have a great deal of respect for the various first nations cultures and wish that they hadn't been so oppressed and separated from their culture in the past. The world today still has a lot to learn from the first nations cultures and I know I will never have enough knowledge to distinguish them properly and understand the differences. I don't always express myself well in my incessant curiosity. ;-)
