"My point is if one's actions bring criticism upon oneself, I would be more inclined to place accountabiliy on the individual who's actions initiated the criticism more so than the one who reacted to those actions"
However, sometimes hateful labels and criticism are used regardless of the actions of the person being labeled. Honestly there was nothing I did in the 6th grad that led to the bully clique deciding to use "Homo" as part of the taunt. I don't assume that someone must have been behaving badly to get labeled. I don't think one can assume that the problem lies predominately with the labeled and can't say anything about the one doing the labeling.
I also look at which words are used for the labeling. That word choice I do think says a lot more about one doing the labeling than it does about the one that is labeled. The choice between floosie and ho resides in the one uttering the words even if the person being labeled was acting in a way that would provoke some sort of response.
Now sometimes people do get their labels by their actions. I just don't know if we can assume Charlie did something specific to Kenny that forced his hand and gave him no choice but to use those words to describe it and no other person could have chosen different words.
