I am no expert of Jrock. Actually, I never listen to it besides maybe one song a friend sent me a couple years ago. However, to me it sounds like Visual Kei, or whatever, is a subgroup of jrock. You know, like how rock encompasses various variations, jrock included.

Sounds like another "everyone else is posers and I'm the only real hardcore person in the world" like most of the "Goth" and "Emo" threads.
