Humanity has a very long and sad history of forced cultural change dating back to the church delegations that roamed the New World in the 15th and 16th centuries who sought to "save" the so-called savages and pagans of the world by introducing them to Christianity. Erasing indigenous culture is not saving them. It is instead indoctrination. It is erasing their culture and belittling their contributions to the history of humanity. It is persecuting them for being different. Instead of support the people and coming to their need, such efforts burden them with other problems.
