I personally do not like black metal. I do personally consider it's messages are dull. YET, I also consider that any person in this world has the right to create, listen and express what they want, neverminding if anybody else likes it or not as long as their forms of expression are not oppressive or intolerant.
The trouble with blck metal is that SOME of the bands and listeners are very intolerant. Yet so are Axl Rose and Dave Mustaine.
What it should be clear is that we are all metal. PERIOD.
