Being "creepy sounding" seems like a very bad reason to be opposed to something. Cryonics is creepy sounding. The mission of the SIAI is creepy sounding (for exactly the same reason as this post, I would say). I don't even see how this differs from aversion to anything strange, which seems horribly destructive in the aggregate.
There may be plenty of other reasons to downvote or criticize this post (empty applause being the main one), but I don't see any legitimate cause for psychological distress. Of course, you may fear that a reader will draw incorrect conclusions about your motivations/beliefs. I don't see why that in particular would nauseate, though--just prompt (actionable) concern.

Making a public declaration is a social act, as is making your own identity be visibly attached to something. When considering the consequences of such actions the 'creepy' vibe or 'ick' aversion provides critically important information about the effects that can be expected.

Clearly the list I've given is incomplete. I imagine most members of the Singularity Institute belong here; otherwise their motives are pretty baffling. But equally clearly, the list will not include everyone.
What's my point? My point is that these people should be cooperating. But we can't cooperate unless we know who we are. If you feel your name belongs on this list then add a top-level comment to this thread, and feel free to add any information about what this means to you personally or what plans you have. Or it's enough just to say, "I want to save the world".
This time, no-one's signing up for anything. I'm just doing this to let you know that you're not alone. But maybe some of us can find somewhere to talk that's a little quieter.
