Hear, hear! I get a niggling aversive reaction whenever I see those terms used when not absolutely necessary and one of irritation when I see them used as 'good/bad' qualifies. Even more so when the alleged 'rational' action is a subjective claim that I don't even necessarily agree with!

And if those of us with 10k karma don't constrain our usage to the first two cases (and in the case of rationalist/rationality with reluctance even then) then shame on us/them!
