As someone who had read Eliezer's OkCupid profile sometime not very recently, I was actually gonna reply to this with something like "well, scientism goes maybe a bit too far, but he does actually have a point"

...but then I just went and reread the OkCupid profile, and no, actually it's wonderfully funny and I have no worries similar to scientism's, unlike earlier when the profile didn't explicitly mention sadism.

Obviously Eliezer is a very unusual and "weird" person, but the openness about it that we observe here is a winning move, unlike the case where one might sense that he might be hiding something. Dishonesty and secrecy is what the evil phyg leaders would go for, whereas Eliezer's openness invites scrutiny and allows him to emerge from it without the scrutinizers having found incriminating evidence.

Also, where are you seeing evangelical polyamory? I'm very much not polyamorous myself, and haven't ever felt that anyone around here would be pushing polyamory to me.
