I don't post much, but I am an avid reader. I don't go to DT or CE for the most part.
May I suggest that you take a look at "The Bilge" over at woodenboat.com? It's a very similar subforum.
If you examine it, you'll find a lot of similar behavior as what you speak of now. There are many, many hurt members (no, not THAT member), and quite a few people who left the forum because of the insults and personal attacks. There is often spillover as posters bring that...
