It's pop music, not history or philosophy. Don't take it so serious. It's meant for the workers in their blue jeans to tap their feet to while they work at their jobs or blow off steam at the bars (who buy all their beer from the same suppliers that sell food to fast food restaurants).

I really hope you're being facetious. If not - what the fuck are you doing on this forum?
I will concede that, taken as a whole, metal is populist. I mean, really, take a look at
Heavy Metal Parking Lot and try to deny it. However, there are certain strains of this subculture in which this is not the case.
When I was in high school, there were two, count 'em TWO, metal head cliques.
One group were the 'career' metalheads: long hair, beards, black t-shirts every day, tough guy attitudes, lots of boozing and drugging, iconoclastic, enjoyed vandalism and debauchery, mediocre to terrible grades in school, liked to posture as free-thinker artistic souls but were pretty much liberals to a tee. They listened to some classic stuff like Darkthrone and Slayer but mostly were flavor of the week trend whores who ate up shit like Goatwhore, Necrophagist, Nachtmystium, Agolloch, etc. I've lost touch with these guys, but last time I checked, one of them was in nursing school but the rest were still dragging their feet in terms of getting their lives together. They'll probably end up blue collar.
Then, there were the nerd metal heads: mostly short hair, glasses, plain t-shirts or polos, genuine nice guy personalities, no drugs but occasional drinking, kind of goodie-two-shoes (not because they couldn't think for themselves but because they knew what was best for them), never got in to trouble with the law, got good grades and were generally smarter than average, fiscally conservative but socially liberal. They listened to traditional/power metal; stuff like Iced Earth, Iron Maiden, Stratovarius, Symphony X, and some prog stuff like Rush. All these kids got into good schools and are getting/have gotten STEM degrees.
I sort of drifted between the two groups. I would go to shows with both, but the fact that the nerd metal heads didn't smoke weed meant I hung out with the career metal heads more often. Because let's face it: flying down country roads hanging on to a sun roof while high was more fun than playing GameCube not high. I don't regret it at all, but if I had to do it all over, I would stick with the nerds, because I was really kind of lying to myself about not being a nerd, and hanging out with the careers caused some crippling habits later on.
Overall, this forum, while it's tastes are more extreme, are more like the nerd types, though there is a considerable blending of the two styles.
That was a terrible troll you linked to, btw.
