I found this article in the Guardian on being "selectively mysterious" about faith. The author focusses mostly on Christianity and God, but I think it's a great question to ask ourselves as Buddhists: how well do we understand and communicate the Dharma? Can we maintain that following the teachings of the Buddha is the way to liberation for all sentient beings...if we also claim that everyone's beliefs are worthy of equal respect and acknowledgement?

Good to read not as opposed to the subjects in the article...but perhaps on the same side as them.
