its a really good subject to be talking about, i felt like you that either many dont get it or there is just too many philosophies that was later brought to black metal, to me the main principals for black metal are hate, individualism , and anti religion its emphasize more in black metal, than in any other form, and unlike other genres that started out against conformity and became apart of it, black metal has stayed pure the longest, so add to all that underground, and you got the black metal philosophy, black metal is too deep to have just one general idea logy, so there is a lot of place for expansion and even for posers to sneak in and taint it...
