The constant blaming of forces like colonization and the residential schools has not always moved the dialogue forward when it comes to ending violence against Aboriginal women. I think a more holistic approach is required that examines all sides of the story, including those factors that might have contributed to Indigenous dysfunction pre-contact.
All cultures evolve and grow over time. Practices that are deemed counterproductive are discarded in favour of more effective ones. Some Aboriginal leaders would be better off concentrating on what will help their people move forward into the 21st century, rather than assuming all cultural practices should be maintained.
