[Nocap]

I knew an ESTJ in high school.
He and I attended several of the same local metal band shows.

He refused to listen to anything else, though he pretended he had wide musical tastes.

In fact, plenty of the people there were S_Js.

I think it's more likely that you'd assume anyone who listens to metal (and has the rest of the rabblerouser/rebel bit to follow) wouldn't be an S_J, not that you actually never met one.
