I think you're barking up the wrong tree by engaging the specific arguments scientism is making rather than looking at what motivated these arguments in the first place. See this comment by scientism:
It's not so much the content as the presentation. The tone is incredibly self-absorbed and condescending. I thought the whole thing was a joke until I encountered the above quoted paragraph with its apparent sincerity. Presumably some of the content is intended to be tongue-in-check and some of it posturing, but it's difficult to separate. There's a compounding weirdness to the whole thing.
I don't think this is actually about Eliezer's preferences being unethical or anything like that, and it's certainly not about broader things like the optimal way of finding a partner with matching preferences. This is about a subset of the population reading Eliezer's profile and thinking oh god this is weird ew ew get it away from me ick ick ick and then writing these kinds of arguments as a reaction. This might sound like I'm being uncharitable to scientism, accusing him/her of giving nontrue rejections, but I think it's accurate because a) the comment I quoted about indicates that this is largely about squick rather than ethics, and b) I also experienced a very strong squick reaction upon reading Eliezer's profile, so I'm somewhat sympathetic to freaking out about it.
I think I've made it clear that I don't find offence in any of the particular lifestyle choices expressed in the profile (i.e., sadomasochism and polyamory), but I think it's more than an issue of mere presentation or the squick factor. My point is that the profile offers some insight into where following LW/SIAI/CFAR recommendations might take you. When somebody sets themselves up as an ethics and rationality expert their own lifestyle and character are going to be subject to especial scrutiny and rightly so. That isn't to say that people should be alarme...
Faith, Hope, and Singularity: Entering the Matrix with New York’s Futurist Set
To my knowledge LessWrong hasn't received a great deal of media coverage. So, I was surprised when I came across an article via a Facebook friend which also appeared on the cover of the New York Observer today. However, I was disappointed upon reading it, as I don't think it is an accurate reflection of the community. It certainly doesn't reflect my experience with the LW communities in Toronto and Waterloo.
I thought it would be interesting to see what the broader LessWrong community thought about this article. I think it would make for a good discussion.
