Blood overcomes flesh
Sulphur overcomes silver
Strictness kills mercy,
And fire overcomes earth
And when the sun sets,
It’s red, you see
An Omen for when the final dusk comes
-Condemner, Omens of Perdition
Sometimes, generalizations are made to serve a greater purpose and help us cut to the chase by eliminating from a contention that which is obvious. In doing so, we arrive closer to the essence of the contention, to the real difference between two things set in contrast; we separate the wheat from the chaff. For example, I may assert that traditionally mercantile communities rarely indulge unpredicatedly, with any degree of true passion, in vocations pleasing to the higher intellect. My justification would be that if one is raised in an environment where material concern forms the overwhelming bulk of one’s idea of a happy life, then it stands to reason that that part of the thinking faculty stimulated by art and other subtle, idealistic musings will remain in an obscured state.
Generalization, though a statistically-oriented exercise, is ultimately speculative in nature, and therefore prone to the odd anomaly. But in this case, the anomaly, rather than upending the original generalization, ends up reinforcing it; in common parlance, this means that the exception proves the rule. If one out of ten people is homosexually inclined, then, leaving out all debate about freedom of choice, the homosexual individual still represents a natural aberration in that sample demographic. Any attempt at converting this state of being into an example of normative behavior, however charitable the reasoning behind it may be, is self-serving and a distortion of reality.
Generalizations or blanket statements can be extended to all sorts of phenomena, including heavy metal, provided the intention behind them is pure and based on accumulated experience. Unfortunately, blanket assumptions are often made because their prosecutor is too lazy to refer to that bank of experience; more damnedly, he might not even have gathered the requisite experience to make said generalization. In such a case, the generalization is an easy way for its prosecutor to leap to a premeditated and, in all likelihood, prejudiced conclusion. This does nobody any favors; not only is it dishonest behavior, but it also dilutes any element of truth that may have perchance existed in the premise behind the original generalization.
