It's difficult to discern, if there's an argument or line of thinking that would induce the "wearing it <their Christianity> on their sleeve" types to rethink their position on this. In any case, I've always found it more positive/productive to cast it in terms of the tension between these two scriptural edicts: #1 "Don't stand on the street corner and pray, that you may be seen of men..." and #2 "Don't hide your light under a bushel..." Clearly, the pro prayer-at-public-meetings types completely ignore #1. It's hard to condense what deserves (at least) an essay length treatment (to fully "grok"), down to a few pithy lines, but resolving that tension basically boils down to humility. The most enthusiastic public prayer types never fully interrogate _why_ they feel this need--the whole thing begins & ends for them with what they perceive as "living" their faith in a demonstrative (performative) way. They pay little--mostly no--heed at all to being the kind of Christian that instead avoids bringing attention to their faith, and yet that faith comprehensively informs their life; the type that _truly_ embody their faith as a lived experience, most if not all of the time. We need more actual Christian _praxis_, not empty performance.
