13th century France is irrelevant because it was, religiously speaking, a different style of society from America since its founding.
In the past, America, unlike 13th century France, allowed multiple parallel religions who each enforced their own moral codes on top of the secular law using behavioral manipulation tactics including shame.
This seems to have worked up until quite recently. In the early 1900s religion was still massively influential in America. Your view on what freedom of religion means practically is a ret con, because people took it seriously up until universal mass secular schooling and electronic media.
I’m not saying we should return to Jesus or whatever, I’m just saying that there is a receptiveness in the human brain to having behavior enforced in a completely non-violent way where the behavior code is entered into voluntarily and can be abandoned non-violently as well, and hmm wonder if it makes sense to leverage that to solve problems that we are currently leaning for the levers of violence to fix (in the sense that state power enforcement is fundamentally rooted in violence, ie the threat of forced confinement at gunpoint).
On you vs others, I don’t have in mind some kind of religiously enforced corporate regulations, that’s obviously ridiculous. I’m referring to religiously enforced individual abstinence from social media, similar to religiously enforced abstinence from alcohol, or from casual sex, etc, all because they are considered harmful (by the people in the religion) to you, not (primarily) to others. If the abstinence was enforced socially the same way monogamy was in the early 1900s (yes, I know there were some exceptions, blah blah blah, it was basically ironclad relative to today), the social media companies would wither and blow away.
