To me the giveaway is the decline in sexual experience among young people. This is like a top line KPI for youth culture and socialization since when people have a lot of positive social interaction and mutual bonding experiences they tend to have sex.
Loads of people have commented on these trends. I’m not pointing out anything new, but I do think a lot of people don’t see it because it’s hidden behind a facade of very visible socially liberal movements that garner attention out of proportion to their numbers. These folks do not represent the mean or the median of the culture.
If you are in the Bay Area or LA or really any metro California city that isn’t a deep suburb your experience might be different. These areas have always been more liberal than the average and enduringly so. The SF Bay was where gay people could go back when there was not just a strong taboo but in many cases real persecution.
Edit: with the last election I think the conservative zeitgeist is going to finally crest, and probably inspire a backlash that will start the pendulum going the other way. Things like politics are the lagging end. There’s also a backlash brewing against social media including dating apps, which are one of the drivers for both youth alienation and promulgation of reactionary attitudes. Right wing cultural fear mongering has excellent memetic fitness on social media.
