I'm surprised nobody else has responded to this one yet.

FWIW, my impression is that these are all good ideas. I'd like to see an emphasis on a theory's merit, however that might be judged. It is possible to say, "I think your theory is wrong, but I'm not sure why," or, "It goes against everything I believe in, but I can't dismiss it just for those reasons," in which case it deserves to continue to run.

(I'm thinking of Robert Tulip's piece in the second instance.)

I would also like to suggest a new punishable offence. This offence is assuming victimhood without justification. Let's have no more "Burn the heretic!" and "This is how Galileo must have felt." Round here, it's generally the messages that get shot, not the messangers.
