A blog post by Alistair Roberts, as curated by Steve Sailer. (Steve's version is shorter and more targeted; the original blog post is the fourth in a series on triggering and suffers for its reliance on the particular issue.)
It seems like a very useful dichotomy, and strongly reminds me of Ask and Guess.
I think the author is spot-on when he talks about "debate as sport" vs. "debate as a sensitivity contest", but I find his obsession with "masculinity" somewhat... weird. He keeps saying that the "debate as sport" mode is the province of men, and the other mode is a province of women... because... I don't know why.
IMO it would've been a better article without the random essentialism.
