Interesting, never heard of Crocker's rules before. Fascinating, and there are parts of it I definitely like, especially the bits around "accepting full responsibility for the operation of your own mind."
That said, this assumes that all communication is between two individuals, and doesn't provide signaling to other members of the group. For instance, if both you and I adopt crocker's rules, but Bob and Susan do not, a new member of our group may assume incorrectly that this type of communication is appropriate for Bob and Susan, or create an environment where the new/less powerful member may be less willing to speak up because of the perceived tone of communication.
It also seems to be position of relative power: one adopting Crocker's rules assumes to be in a position where certain types of speech do no harm to them.
