Snidget, If there was nothing you did in the 6th grade to warrant the ridicule you received then I feel very bad for you and those bullies were 100% at fault for what they did.
I realize I am in the minority when I say this, but I personally have never been caught up in the specific words used by individuals. Although some may appear harsher than others, I focus on the what that word means and if two words give the same indication, then it's the same in my mind. Like I said, I realize that may not be the norm, but to each their own.
In the case of Charlie...I don't believe we are talking about something Charlie did "specifically to Kenny". We are talking about one's actions in general causing ridicule. I think Charlie having his nose up Marcus' butt like a dog in heat would constitute as actions that may constitute a label.
Let's also understand that in real life when an action or situation creates any uneasiness, you can get in a car and drive away or get as far away from the action as possible to avoid the situation. Such is not the case on Survivor. The players are confined in a controlled enviroment and they are unable to get far away from the action. So if a derogatory word is uttered in disgust I would consider that more excusable in this situation. But as I said before...to each their own.
