Having lived in the United States long enough now, I've watched bad faith actors use culture to effect very negative, antisocial outcomes, with absolutely no action taken. I have watched each click of the ratchet, as bad faith dissimulators tell us that each new change isn't really happening, it's a crazy conspiracy, and also it's good that it's happening. Watching friends and coworkers install the latest progressive code updates makes me feel like everyone around me is being replaced by pod people. These are people whose slogan is "change", who insist that I am the radical one- its quite nuts.
People who believe in nothing also will believe in everything, it's why cults proliferate in times of social deterioration. We all need social norms and rules to tell us what to believe and do. The deluge of data we receive as humans is impossible to sort and interpret without a hardened moral framework. Most people lack that, so when someone comes along with clear, uncompromising rules, they are drawn to that- strong horse, weak horse. Whether you can be have your mind taken over like this by rapid norm reversal is pretty much the criteria for whether you are fully human or just some kind of animal. True nihilism isn't hopelessness- it is having no anchor.
