LW historically has had a habit of choosing examples with shock value beyond what's necessary to make the point; granted, this no longer seems quite so fashionable for new top-level content, but it does remain noticeable in comments and in older posts, including parts of the Sequences. I view this habit as basically a social display: a way of signaling "I can handle this without getting mind-killed". Now, let me be very clear: I do not regard this as intrinsically destructive, nor do I place substantial terminal value on avoiding offense. But I do think its higher-order effects have avoidably reduced the quality of discussion here. The fundamental issue is that not everyone here is equally able to avoid derailing discussions when exposed to topics like, say, torture. Even people who are generally very rational may find particular subjects intolerable; judging from experience, in fact, I'd say that most of the people here have one or two they can't handle, including myself. Avoiding these is part of our culture when they overlap with talking points in mainstream politics, and that's good; but there remains a wide scope of weakly politicized yet potentially mindkilling ones out there, many of which we've historically thrown around with the gleeful abandon of a velociraptor plunging into a vat full of raw meat. I think we should stop doing that, at least to the extent that we avoid conventional politics and for most of the same reasons.
