Culture is dynamic, not static. It has changed over time and values have moved all over the place. You do not own a culture, it is not yours. You can tell others not to adopt your culture but they don't have to acknowledge. I also take the stance that it is an effective way of iconoclasm that helps to remove old culture that divides and allows for a new common culture to take it's place, hence removing the deviance until these groups split up again. What are your thoughts?
