The hipster has one salient trait: ironism. Whatever everyone else is doing, he is not. He uses this trait in a passive-aggressive way to force acceptance through provocation. Where normal people gather, the hipster will show up looking as weird as possible, hoping that someone will say something because he knows that social pressure is on his side. If he is criticized, he can use the dominant paradigm of our age (individualism) as a weapon and claim the other party is bullying him, when in fact it is the hipster who is starting the argument by deliberately being unusual, different and “unique.”
This approach combines some of the ugliest aspects of human behavior. First is bullying, because the hipster is waiting for criticism so he can say, “Look boys, it’s just like in Napoleon Dynamite, the popular kids ganging up on all of us accepting and tolerant freaks! I’m just different, why am I the victim here?” and have an instant army of angry complainers to attack the critic. He has government on his side, which supports being freaky any way you want to so long as you pay taxes and don’t murder, and popular opinion. Second is egomania. The hipster is not concerned with truth, the future, the past or fact; he is concerned with social appearance, which serves as both his justification for existence and his weapon against others.
SJWs arose when people realized they could politicize this hipster approach. In addition to looking freaky, they took extremist positions within the dominant leftist+consumerism individualist ideology of the West. This attitude combines the liberal social attitudes of the left with the market-oriented attitudes of the right, and creates a nasty hybrid which supports freedom above all else, so long as profits (and taxes) are made. SJWs are not “different”; they are a different variety of the same. This allows them to style themselves as unique and deep thinkers without offending any of the current attitudes of society, but because they manifest these ideas in physically odd appearances and extreme versions of those accepted views, they provoke criticism and can then attack, increasing their own power in the process.
When SJWs decided to adopt metal, their first goal was to style the rest of us as aggressors. That way, the hipsters could passive-aggressively claim to be victimized and begin the group counter-attack. Their problem has been that metalheads use apathy as a weapon. We view this society as moribund and on its path to self-destruction, and so tend to consider SJWs irrelevant drama. On their second assault, SJWs refined their attack to “if you do not participate in our crusade, you are bad and must be destroyed.” This is why we now have articles on a regular basis talking about how metal is not accepting enough and must be reformed.
All of this comes as metal struggles with its own refinement, namely the smooth fusion of hardcore punk, progressive rock and heavy metal that was underground metal (death metal, black metal, grindcore and doom metal). The SJW hipsters do not like this fusion because it is too far from the warmed-over 1960s protest rock that they favor — let us face facts and admit that emo, and anything tinged with it, is basically Bob Dylan worship. Metal rode on a wave of energy caused by the need to make such a fusion, but once it was achieved, had no idea where to take it further. There were no further (coherent) extremes, nor new musical developments to occur. As a mature style, it is still waiting for fresh energy to revitalize its lexicon of techniques and conventions and put them into a new language, and while some bands have forged a path in this direction, most continue to either re-hash the past or re-hash other genres with metal flavoring. For this reason, SJWs infest it, because they sense a dying trend they can turn into something they control.
