> maybe that would help people behave better, with real-world decorum, in those specific identities

I don't think that would be the result, really, because when sites do have real identity requirements, it doesn't increase civility much, if any.

I think it's the absence of a physical presence that makes people feel OK with being less civil. Emotionally, it doesn't feel like you're talking with real people.

But I don't know.
