If by "question" you mean critically then I can't think of many situations where you can question critically anyone who has some kind of power over you. The only way around that, if you really want to be heard, is to go to the person that has power over them.
And therein lies the problem. Religions have a free pass in many ways like discrimination for eg because God is their boss and only the highest ranking in the group have access to that boss - kinda sucks doesn't it.
