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.
Torture is a uniquely good tool in thought experiments, when you need something bad, and I refuse to give it up.
Death is too complicated (and therefore invites too much hypothetical-fighting). There're questions of what quality of life you're missing, how long you would have lived, etc, and worse yet, some people think it's a good thing. No one* thinks torture (of the average person) is a good thing. When people say things like "I want to go on living no matter what my life is like" the only correct answer is extremely unpleasant experiences, whi...
A long blog post explains why the author, a feminist, is not comfortable with the rationalist community despite thinking it is "super cool and interesting". It's directed specifically at Yvain, but it's probably general enough to be of some interest here.

I'm not sure if I can summarize this fairly but the main thrust seems to be that we are overly willing to entertain offensive/taboo/hurtful ideas and this drives off many types of people. Here's a quote:
The author perceives a link between LW type open discourse and danger to minority groups. I'm not sure whether that's true or not. Take race. Many LWers are willing to entertain ideas about the existence and possible importance of average group differences in psychological traits. So, maybe LWers are racists. But they're racists who continually obsess over optimizing their philanthropic contributions to African charities. So, maybe not racists in a dangerous way?
An overly rosy view, perhaps, and I don't want to deny the reality of the blogger's experience. Clearly, the person is intelligent and attracted to some aspects of LW discourse while turned off by other aspects.
