"I think you could more accurately be described as a perceptively independent observer who enjoys pointing out where a generally accepted opinion is, if not wrong necessarily, at least questionable. Contrarians are more indiscriminate. Maybe the word you were looking for was impish."
Wrote Luke Lea in the comments to "I resist Glenn Loury's label for — me — 'contrarian,' explain why, and offer an alternative label, which he then readily slaps on himself."
That felt very accurate to me... except for the suggestion that the right word is "impish."
I wonder if the word "contrarian" felt wrong to me because it seems indiscriminate — like someone who disagrees for the sake of disagreeing. I'm discriminate, but you might not see the way I'm being discriminate. I'd have a little trouble myself explaining exactly what gets me going disagreeing with people, but it has a lot to do with whether those people are pleased with themselves and think they're better than other people because of what they think.* Smugness, self-righteousness, identification as one of the good people, looking down on people who don't agree — that brings out the contrarian in me.
Anyway, "impish"... it means "Having the characteristics of an imp; pertaining to or characteristic of a little devil or mischievous urchin." Sounds "a trifle too satanic" (to quote The Rolling Stones).
* Yesterday was a good example, when everyone was scolding Chuck Schumer for demanding that a rich old lady tell him why she voted for a liar. I said "I think it's nice that Chuck Schumer displays his opinions and personality in full public view." In the comments, I even said "I cop to trolling on this one. Used the word on my own talking to Meade before I read this." ("This" = Paco Wové saying the post needed an "Althouse trolls her commentariat" tag.)
