And that those people who are not Christians but have a church wedding are just doing it because they want to be the centre of attention in a lovely white dress, to walk down the aisle with music playing and that all that stuff the vicar says about God etc is irrelevant because they don't actually believe it but they're going with the flow and it's traditional.
AIBU to think it's a facade - vicars go along with it because it keeps the church going, couples go along with it because it's tradition and they can ignore the religious stuff and true Christians probably get a bit annoyed but accept it?
