You seem to be saying that religions are open to having their dogmas questioned and then growing from that, something that they are famously not open to (kind of the whole idea of a dogma).

Obviously 'Not all religions,' etc. However the Catholic church is notoriously dogmatic. Usually the more you press a dogmatic group to change, the more they dig their heels in about it. It's only when the organization is wounded by a schism or massive loss of membership do they suddenly start getting word from heaven that God has changed his mind.
