They needed to spend more time at hessian.org -- they're trying to make death metal into tedious rock music.
That's always the problem with mainstream media's representation of heavy metal: they want to castrate it and make it conform to a liberal worldview where all statements or thoughts not related to upholding the current societal structure are just escapism. Of course, the double-edged sword in this is that by portraying that antisocial opinions of hessians realisticaly, it alienates the average person who can only see the superficial aspects of the culture which conform to their stereotype of what metalheads are or should be.
There's really no solving the issue; those that will come, will come. Now the question is which is more harmful?
Also, I love the blatant attempts at jamming metal's square peg into egalitarianism's round hole, evidenced quite obviously by their emphasis that some females choose to be involved. Once again, an attempt to pervert metal's ideals to fit with civilization's.
