They are all fucking dead, regardless of which flavour of superstition.

We roped many commonwealth countries in to help and, as some found out, decided protecting them in return wasn't strategically advantageous in WW2

RBL isn't a religious body and judging by his turban has at least one Sikh on its board of trustees. The Church of England is, regrettably, the state superstition and has links to government and royalty, hence their involvement, regardless of the wishes of RBL or anyone else for that matter in state events such as remembrance hand wringing.

The idea of "most people" wanting religion mixed into it is a groundless comment with no basis. The mental leap that people want religion at the event on the basis of attendance by old men in frocks is like saying I go to football matches because I like the smell of the urinal blocks.
