The simple bottom line is that the moderation here is what it is. Our Rules of Conduct are what they are. Until such a time as they are changed, we're going to continue as we have been doing for the simple reason that it promotes a hospitable and productive forum. The boards here have thrived on this method since 2003, and we get multiple compliments every month on how nice it is that the usual argument and derision so prevalent on other homebuilt fora generally doesn't happen here.
Short and sweet: This place is a certain kind of forum, with a particular style. If you like it this way, as 4,625 active members seem to do, hang out with us and enjoy the fun. If you want to brawl and call each other names, you know where the door is.
Himat: Noted on the suggestion regarding locking a thread vs. deleting posts. We've generally opted for the former, since it allows the discussion to continue, but obviously there are situations where that can be counterproductive. Thanks for your input.
