Lot of room to speculate.
The axis is childlessness/more concerned with online social standing/less patriotic on one side, versus having kids/being more patriotic, fewer accounts of depression.
Much of the push for parasocial relationships is, I believe, the result of people not having kids to come home to but living life online. That also is responsible for the fear of "social death", e.g. online ostracism. People who come home to kids and grill with their friends on weekends don't particularly care about conforming to the beliefs of strangers online.
Read carefully, I didn't disagree.
> it's childless people who see therapists more.
Possibly because they have more free time and disposable income.
As I said, there's a lot of room for speculation, probably best to avoid sweeping generic explanations based on keyhole PoVs.
Now, people who are younger and urban tend to also be childless, but if you control for child bearing, you will get some eye opening stats. There is also a correlation with depression and the number of visits to therapists, but that could also be due to the loneliness of being childless in a major urban area.
