Can you link to an example of someone using it as a compliment?
Yes:
He is an erudite, controversial and most of all contrarian social critic and writer.
Yes (a self-description rather than a compliment to someone else, but clearly intended to be read as a worthy attribute):
As a contrarian rationalist
Here is someone excusing themselves for not being contrarian:
Not everyone can be a contrarian rationalist.
In the first link you quoted me describing Moldbug, I should clarify it was used as a put down. I've said quite explicitly in other posts that I strongly agree with Hanson on contrarianism.
In the second link the person continues:
The result is that I'm biased towards contrarian theses, which I think is useful for improving group rationality in most cases, but still isn't rational.
The third is a good example but it is in an article talking about how weird LessWrong is for its love of contrarianism.
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
