I think it matters in this context. If these people are contrarian simply because they happen to have lots of different views, then it's irrelevant that they're contrarian. If they're contrarian because they're DRAWN towards contrarian views, it means they're biased towards cryonics.
I agree it matters in this case, but it doesn't matter whether we use the word "contrarianism" vs. tabooing it.
Also, your summary assumes one of the points under dispute: whether it's possible to be good at arriving at true non-mainstream beliefs ('correct contrarianism'), or whether people who repeatedly outperform the mainstream are just lucky. 'Incorrect contrarianism' and 'correct-by-coincidence contrarianism' aren't the only two possibilities.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
