Some people say “no-nonsense” as if it's something to be proud of-- like their no-nonsense attitude was somehow intrinsically superior to another person's more nonsense-friendly way of doing things. These are the folks who would rationalize every aspect of life. But look; rationality is a system invented by humans in an attempt to explain reality. When the real deviates from the rational, it's the system of thought that has failed. And when observed phenomena deviate from the predictions of your accepted orthodoxy, it's no use standing there slack-jawed saying, “This can't be happening.” That's simply nonsense.
