They do. Ted K, Pentti Linkola, Thomas Malthus, Osama bin Laden, Adolf Hitler, Charles Manson... all are very metal, and all are demonized by society.
Interestingly, there's a public reality concerning each: the illusion of what they did (Charles Manson killed people) versus the reality (Manson is alleged to have ordered the Tate-LaBianca killings, but did not take physical part in them). Same way with Hitler: his enemies would have us believe he was a raving maniac who hated all non-whites, but the truth is he was a gentle man who loved Germans and would do whatever was necessary to preserve them, but was live and let live with everyone else...
Burzum fits this category also. From a different angle, so does Demilich.
