I don't think the problem is something that can be patched with Crocker's Rules - I think the problem is lazy reading. That many dedicated contributors are lazy was shown off by the responses to MBlume's "The Fundamental Question": a substantial fraction of top-level responses interpreted the post as community-building instead of philosophy, a misinterpretation which only makes sense if they completely missed the entire first paragraph. Given that regular comments are read with even less care as a rule, anyone who doesn't make what they say sound obviously true to this community will get slammed, correct or not.
