I'm not talking about deist intellectuals and their opinions, or academic theology, or about places other than NW-Europe (New Mexico?), or a few big tourist tickets like Santiago.
I'm talking about the popular Christian day-to-day practice of regular people of NW-European communities, of which I can witness the last strange hours in my own community.
It's hard for me to come up with numbers beyond the kind of polls shown in the Guardian article or the drop in callings. It's not like we have centuries of headcount records for all the local events, cults and customs that used to exist here, the amount of tresses tied to chapel walls, or logs detailing the time and effort the local farmers, notables and grandmas spent decorating chapels. There have been no double blind control studies of how going to the village church made people's daily behavior slightly more mellow or made the community tighter here. By now there's mostly old pictures, living memories (less every year) and a rapid dwindling of what little remains today.
The edited stuff you refer to was a sarcastic quip along the lines of "Now that Christianity is gone, I'm sure celebrities or the state will tell us what to do." I removed it because, reading it back, I thought it detracted both in style and content from my main point.
Namely my prediction that future people in my community will regret current people having turned their back on this heritage so recklessly. They may try to reconstruct some of it, but it will be hard without continuity. I can see that happen even if Christian belief itself never bounces back. (Which would actually put such efforts at risk, by making them prone to political recuperation.)
