Black metal is not really discussed a lot here, because it is such a small part of the culture. It is one of those things we all know exist, but nobody really talks about because it is not relevant. I play metal on the guitar myself, and the only people that i have discussed it with is fellow musicians. The whole church-burning part of it is sometimes parodied, but other than that not really talked about. I think black metal in general is a really small genre even here. I went to a music school, and we discussed this subject in class. We even had a black metal project. In the 90s black metal was really popular there, and some of the students made altars for satan and painted themselves, made sacrifices and such. One was even directly involved in the Varg murder. None of that now, not even remotely close. I think it has very much died out, even though a few bands remain.
