the real answer to the original post is that, from past experience, if a thread gets out of hand, and you delete all of the offensive stuff, but leave the thread open, it will simply pick back up where it left off.
time and again it has happened. it works best to delete offensive or heated stuff, and close the thread. no one needs to be banned for getting upset, though we have had some people who seem to always be in the center of controversy and then a decision must be made. WPB really is an institution in our hobby, it's not in his character to be mean spirited or chronically problematic. I'm sure there is a certain amount of weight placed on a desire to keep him here, but that's a good thing, knowledgeable and experienced people are worth keeping if you can. I think irascible may be a better description than many others for Walter, I for one hope he gets over being upset and comes back. I also understand the tendency as I get older to lose patience more quickly.
while I don't think favoritism is the right word, this isn't a democracy either, some people have been here a long time and contributed a bunch, and it is true made friends here, and that does carry some weight, it has to.
I also agree that some of the shenanigans have run off some of the most potentially valuable members over the years, but that usually amounts to Scott trying to be fair to the new or less polished guys than favoring some old time collector or friend. you'll notice there are more new guys than old guys here. keep that in mind the next time you want to talk about favoritism.
and I also wanted to point out that I have more thumbs up than Bikewhorder...
