[Terminology] AP has defined several common terms for its reporters' use ("alt-right", "alt-left", racism, white nationalism, white separatism, white supremacy, neo-Nazism, antifa)

Is this good? If not, why not? Can we add other related terms?

racism
The broad term for asserting racial or ethnic discrimination or superiority based solely on race, ethnic or religious origins; it can be by any group against any other group.

white nationalism
