Why does a Mormon have to be Momorn and an African American an African America. Can't they just be Americans and that's it?
The ability to change belongs to the people empowered by the social structure. Calling yourself an American doesn't stop people from checking you for horns. Calling yourself an American doesn't stop police from pulling you over based on skin color. When it happens a few times, you can shrug it off. When it's a daily thing, it's a problem with society.
