Oh look! There's a Wikipedia article entitled "List of political ideologies". Let's go look at that!
Wow, there sure are a lot of them...
The list contains everything from "Jewish anarchism" to "Ecofeminism" to "Islamic feminism" to "Queer nationalism" to "Christian communism" to "Libertarian socialism".
Each one of those dozens and dozens of links leads to its own Wikipedia article, no doubt assiduously maintained and argued over and edited and re-edited by people who consider themselves devotees of the purest form of said ideology and who denounce each other as "Splitters!" and each and every one of them sure that they have decoded the message on the back of the cosmic cereal box.
I think it might be simultaneously the funniest and most depressing thing I've stumbled across on the interwebs so far this week.
