The Popularity of SI

Does anyone else feel invalidated by all the reports of a "dangerous teenage trend on the rise" all over the media? I'm all for awareness, but many have said that they began cutting after hearing about it from a friend or knowing another self-injurer.
When I cut for the first time, I didn't know what SI was. I would hate to feel responsible for "giving the idea to a friend." The influx of self-injury cases seems to minimalize the underlying issues in the eyes of the public and professionals as they focus on the stigma of the behavior. Yes, there are some who SI for attention because of this very stigma, but I feel fed up with the media's interpretation of SI and the public's consequent opinion.
