I gotta admit, the original poster's comment holds some water.
The recent surge of popularity in dubstep in the US has brought a new group of kids to the rave scene. Recently it has been a lot less PLUR kids at events and more regular party bros who show up that recently discovered dubstep. And naturally they are interested in the drugs available, which in turn leads to a lot of them selling. As many of the other posters here have mentioned, I don't buy at events ever, so this whole ordeal doesn't really affect me. However what does bother me, is the fact that these new kids coming to the raves are really only interested in the dubstep DJs, and don't appreciate some of the great DnB, hardstyle, and psytrance mixes going on. If the bros are happy taking their DOx/2c-x/shit mixes thinking it's molly, more power to them.
