Okay, I have one:
Buddy used to visit a chat room. Because Buddy is very sensitive, he always noticed the small handful of posters who were nasty, self-serving and condescending. There was also a poster or two who were very in-your-face and arrogant, thinking that every thread they wrote was just what we’d all been waiting for. While most people on the site were polite and caring, these posters were either ignored or reprimanded in light and rare postings. Because they didn’t respond well to reprimand, people generally seemed to work around them.
One day another in-your-face poster started posting. This poster was neither rude nor arrogent but many found the posts annoying. Because this poster was obviously young, the other posters who were always quiet for the nasty and rude posters, seemed to feel they had a green light to put this poster in his place. One poster chose a nasty and condescending way to “politely” reprimand, and the floodgates opened. Even those who normally don’t condone this type of rudeness seem to be justifying the posters rudeness. Buddy, who silently found this poster annoying, was surprised at the contrast between these different responses. He discussed this contrast with a psychologist friend and they wondered whether this was “herd mentality”, “justified bullying”, or just bad middos.
