We've lost our way somewhat in the West. I can't work out if it's the need to replace religion with something meaningful. That atheism just isn't doing it for many people. ( I am an atheist). People seem rudderless, without meaningful direction. - very interesting comments.
Douglas Murray was interviewed by the two guys on Triggernometry (a youtube channel) and Murray was asked what things we in the West should talk about but don't. And he brought up this same issue that you've brought up.
Personally, I believe religion to be nonsense but if we recklessly tear down all traces of religion, including culture so that the UK isn't even 'culturally christian', then we'd better make sure we have something decent to replace it.
