Actually, there is. And it's a big reason. That's how minority cultures die out. And more often than not, it's intentional by the majority to do so. Native Americans adopted and given "white" names and dress. Taking pagan holidays like Winter Solstice and making it the celebration of Jesus's birthday (despite him being born in August), and things like christmas trees, and presents, and dressing up for Halloween.But there is nothing wrong with emulating culture.
Really, the list is pretty exhaustive of how cultures in history have hijacked other minority cultures as a way to eliminate their influence and culture.
