In my experience, fundamentally a lot of people are just like this regardless of age, and you notice it more when vetting romantic partners. Especially with how faggy people are about politics these days, and how it comes up all the goddamn time, you get a pretty quick sense of how people think about deeper topics. I suspect very few people go from being complete niggercattle at 20 to freethinker chads at 30 (there's some shift, but I bet it's a lot more incremental than that).
I dated my last girlfriend from her early 20s to her basically being 30 (wall joke lmao), and I almost feel like her opinions got more retarded as time went on, but with the honesty of hindsight I think she always thought the same way and I just glossed over it because I cared about her and wanted to think well of her. And, similarly, I have to admit that a number of my good IRL friends are kind of retarded in the same way - they bring up the news story of the day, chime in "haha republicans bad am i right", and circlejerk about it without really discussing anything meaningful for the most part. They mostly love the new pop culture thing, some of them even use Twitter, it's a disaster.
But the thing is that we have enough in common and get along, they're my good friends and despite it all there aren't really any problems. But once you have to tolerate someone constantly to cum in them, and eventually for like 8+ hours every day when you live with them, the list of things you can deal with goes way the fuck down. My friends can be retarded on their own time, but if my girlfriend starts watching TikTok for an hour+ each day, living in a monastery starts looking real good.
