Conservative types are usually more dogmatic. To me Buddhism is a liberal religion and should be open to many interpretations, even within one specific tradition. Ajahn Brahm often goes against the grain, and personally I think that's why loads of people love him, because he is unorthodox.
"The original heart/mind shines like pure, clear water with the sweetest taste. But if the heart is pure, is our practice over? No, we must not cling even to this purity. We must go beyond all duality, all concepts, all bad, all good, all pure, all impure. We must go beyond self and nonself, beyond birth and death. When we see with the eye of wisdom, we know that the true Buddha is timeless, unborn, unrelated to any body, any history, any image. Buddha is the ground of all being, the realization of the truth of the unmoving mind.” Ajahn Chah
