Ok, if you really want to ignore my point about memes and how they reflect poorly on those who use them for political messaging, we can talk about words.
Stating that a word was inventing by a rich person doesn't make it invalid, stating that the CIA promoted an idea also doesn't make it invalid. Nevertheless, if totalitarian isn't a word we are allowed to use in you doubleplusgood circles, how about you give me a word that describes a country with a single party, ruling in perpetuity? I would say memes are useful for [insert your word here] propaganda
