I agree, but I think something the hn crowd misses is that a huge chunk of young people are invested in something like your Reddit bubble, or at least that's true with the mostly trans/queer twentysomethings of Seattle that I hang out with.
It's hard to ignore the tread that the younger a group is, the more being too online is just the default. You can't opt-out of the reality distorting effects of algorithmic content consumption when it is replicated by everyone you meet at school. This problem is especially bad with sex and gender relationships because of how well those topics perform on social media.
Its a depressing time to be a kid, and even more so to be a teenager. I think nerds (like you), queer people (like me and the author), and other terminally online people are canaries in the coal mine for what will become the new normal.
Queer in your 20s in Seattle is the prime demographic for a lot of these online subcultures though. If that's your crowd but you dislike the very online mores I definitely feel for you. A lot of the rest of us have the luxury of having friends not in these bubbles.
I have a younger sibling who is in their 20s but not very online and only one or two of their friends are, even though they constantly use social media. I think queer groups tend to be a lot more line than others. Leaving Seattle will probably help too but much of the US is unfriendly to queer folks so there's probably only a handful of other places to go.
