This is because most people are mental midgets who have no real personality and bend over backwards to feel included and very very few humans think of anything outside of physical appearance. [...] This is the power of trenders. They have acquired the mental virus that makes them think they must be like the outgroup and all of normal society is wrong and bad and they destroy whatever they get into and make it worse for everyone.
It's always been monkey see, monkey do. Always. Any behavior that can be copied is potentially a mind virus. Memes instead of genes, but very much a virus. Any behavior that will help you fit in is by definition contagious. Any behavior that gives you that while also doing damage is now virulent. It was always memes.
The reason "old wisdom" works is because those particular memes were stable enough to protect themselves while serving the cultures and societies that hosted them. Much like the hypothesized virus that became the eukaryotic nucleus, those memes were more or less symbiotic.
Here and now, we've abandoned them because of the memes of the 19th and 20th century. Yes, there was room to improve. No, the way we've done it is clearly worse. The situation we are in is probably best described as a contest among people who can actually think for themselves to influence the "mental midgets" to take up memes that actually help instead of hurt society, and themselves.
Memes that sterilize those infected obviously can not last without spreading. Memes that destabilize societies clearly will not last if other memes exist that are more stable and can out compete through attrition or by changing morality. Thankfully, those do exist.
The question is which set of regulatory memes will we take up? Some Christian resurgence? Something Islamic? Post-religious synthesis, perhaps with a self aware bit of sanctioned religion for the masses that need it, so kindly and shrewdly delivered by nonbelievers who see the need for a God?
Nobody here can just pick one and make it happen, but we do have influence, however slight. You tell me what you want.
