Reply to RANT: EDM & Drugs stereotype

Just a rant, the stereotype that fans of electronic dance music fans do drugs pisses me off, a lot. It's borderline discriminatory in some cases. The event that inspired this rant happened at my school (I won't name for obvious reason). A VERY small group of kids at my school (less than 10 including myself) are devoted edm fans, the others mainly pop, rap, rock, basically mainstream stuff. Well me and 4 other friends went to an edm festival a few weeks ago, (house/trance, some dubstep also). Well, my school conducts "random" drug tests on students. It just so happened that the Monday after the festival that weekend, all five of us who had attended were drug tested (administration is obviously aware of our musical tastes and that we went to said festival). I didn't speak out to at the school for targeting us like this but I wish I could. All five of our drug tests came back negative in all categories (marijuana, cocaine, amphetamines (including MDMA), opiates, steroids, and pcp). It was obvious they were targeting us as they knew we had attended the festival. I myself have never done any of those drugs and don't care to really but if you want to that's your prerogative, not my choice to make for you. It just aggregates me that electronic music is STILL singled out like this and people act like other music scenes don't have any stigmas about them. I'm not trying to call out other genres (as I listen to them from time to time) but it's just annoying that we are still ALL treated like drug addicted heathens. Rant over. Feel free to chime in.
