It's just another variation of the "intelligent discourse" idea that gets bandied about quite often on these sorts of boards.
We have every right to communicate, no one has verbally attacked anyone else, if it really bothers you just skip on by instead of taking the time to make sure we're aware that you're judging everyone involved in the conversation.
This is an example where I'd far rather people just downvote each other and move on than post these bickering threads.
Maybe I'm wrong though.
