Here's how I feel about it: If someone is posting about someone who did something rude and someone responds with "Oh, (that person who did that rude thing to you is) such a special snowflake!" or "What a jerk!" (keeping it within the bounds of the filter, of course) I'm okay with that.
On the other hand, let's say something like this happens:
OP: "This rude thing happened to me the other day. Here's the story..."
P: "Oh, my heck. You are such a drama queen. Stop being such a Special Snowflake!"
This is NOT okay. We post on here all the time about other people. It's kind of the point of the website. It's how EtiquetteHell started... We also post about them in a way that there is pretty much no way that they could know that the story is about them, I would hope. But when posters start calling *each other* names is when it becomes so very much not okay.
Edited to add a stray word. I don't know how it got away.
