I typically stay out of these types of threads since they rarely solve anything but...
I will say that Pinside does not have the corner on the market in drama and negativity. Other club forums I belong to do suffer similar drama and negativity.
I feel that people, in general, treat people differently through email and forum text. People that would never say mean and/or negative things when standing face to face with someone, can type the rudest, mean-hearted comments. I guess it is much easier to be insulting and negative through text on a screen than standing in front of them when you can see their reaction. I also see this in the business world with email and conference calls vs face to face meetings so the trait is not exclusive to pinball fans.
