Over at Patriactonary, Will S did a post about bullying. One of the points that he makes is that the term bullying is getting the rape treatment, which is to say that much like the word rape, it's being used to cover a broader and broader range of activities.
One of the interesting things about language is how one language is compared to another in worth. When I was in Greece, one of the natives told me that the Greek language has gone through several recorded fazes. Early on there was Homeric Greek, the language used in the Iliad and the Odyssey; then you had Koine Greek, the language the New Testament was written in; Medieval Greek; and lastly Modern Greek, which is what is spoken today. The interesting thing about the Greek language through history is that instead of advancing, the language has devolved, and is today more primitive than it was in the time of Homer. When I asked how one measured whether a language was superior or inferior, he said, among other things, that in Homeric Greek one could communicate a thought more precisely with fewer words.
The reason Will S's article made me reflect on this is that those who push for various PC causes, such as stopping bullying, are always trying to bring more and more things under their favorite buzz word categories. “You might not think it, but that's racism/bullying/sexism/harassment/etc. to.” The end result is to take away from the precision of the conversation, which then takes away from the precision of thought.
The desired end effect is to cut off people's ability to think about these issues, and instead have them simply react.
