This discussion, and the language policing that goes along with it, became tedious decades ago. The simple fact is that you guys are the ones arguing for narrow definitions of words that in fact are not defined narrowly in common usage. There's no consistency in it, and it has nothing to do with clarity. The organizing principle is that if you associate a word with religion, you don't want to use it, and you don't like when anyone else does either. You can ignore that obvious reality but I promise you, most people see it.
Since you think you have a consistent, inambiguous definition of belief, what is your definiion?
