I applaud you for writing this. It is certainly the right thing. But I also think virginiadear has a very good point. "They" (whomever "they" may be) always think their actions are justified. They always think they're in the right. They always think the shunned person deserves it. They always don't think they're being mean but "justified" by the terrible slight.

I have to admit that I often find it all too reminiscent of high school and I tend to go my own way, just like I did back then.
