A couple of good examples are the belief in capitalism among libertarians and the belief in Communism among Marxists.
“Belief” in something that has so utterly proven itself to work? Calling one of these a belief flies in the face of this statement entirely:
are so firm in their beliefs that no piece of evidence would ever change their mind about anything.
How much evidence does one need to “believe” in capitalism? How much evidence does one need to “believe” in Communism? (Interestingly enough, one of these is capitalized as a proper noun, or rather a true ‘ism’ and the other just is). Listening to people argue about the merits of capitalism versus Communism is like listening to an old white guy try and argue that the word honky is as bad as the n word he can’t even utter. One is objective worse than the other, but their is a ‘belief’ in the false equivalence that they both deserve equal time.
The problem you ignored throughout the piece is how to qualify so-called ‘evidence’.
