I did think about Marxism, but why would it be less likely to explode in my face? It's also a modern political position. I decided to go with the Republican case because it was where I originally noticed it and as far as I can tell the most archetypal example. I considered it acceptable because I'm not actually saying the Republicans are wrong about any particular policy issue.

Would you prefer that next time I include two examples, one attacking either "side" of the political "spectrum" next time? Or can you think of some historical example that would be as immediately recognizable to everyone here as the Republican one?

I'm also getting a little sick of always using groups disliked by the entire Less Wrong community as examples (eg Christians). Yes, it makes it easier to read without getting angry, but it seems too potentially dangerous to come here and see something else accusing Christians every night. I don't know what to do about it.
