All of the internecine bickering, theoretical hair splitiing, and other word games that anarchists of different tendencies engage in can make for decent message board fodder.
I think it's more a matter of having a rational world view that fits the visible data as opposed to a theoretical model that will never work (communism) or an idealized version of the past (Republicans, esp. Reagan Republicans.)
I was listening to Mike McConnell up here, and he was saying that Reagan's accomplishment wasn't so much that he reduced government, but that he restored America's confidence in herself. That is, he restored the confidence of the people in their ability to make a better and brighter future for themselves.
Of course, there are those, who I will not point fingers at, that take evolution to mean that people are no better than animals and must be fed, watered and treated as such. Instead of being treated like the only rational, intelligent, sentient species on the planet.
