I disagree strongly (and I did not grow up in a religious context). I feel that pointing out the flaws in basic assumptions allows the to be identified and (one hopes) addressed; the use of religious metaphor can help some people frame it properly.
define this. Those metaphors certainly do "frame" things, but what criteria is being used to make determination if that framing is "proper"? My view is that it frames thing in a loaded biased way that presupposes the solution, which is atonement. There is a clear and unambiguous bias towards the solution you've already decided upon by using that framing. Basically, you've worked from the solution backwards towards the framing that will convince others to arrive at your chosen solution.
