I agree and I have argued that in the past. I'm just saying that we don't have a problem with it. It's only every month or so that someone comes along making excuses and we look like reactionary crybabies when we jump all over them at the moderator level. Personally, I would rather just leave it alone and let people discuss without intervention. It's like having the fire brigade on retainer to light a candle once a month. Most threads have only 10-20 comments so does it really matter if there is one lonely dissenter every so often?  I am very open to keeping the rule. I want to put this idea out there, but I understand if it rubs most people the wrong way.
