I understand and agree with your fears Icon.    As a person of faith, I have never expected, nor ask for, special treatment.  I can pray anytime I want, I don't have to stand on the street corner so everybody can see me.   Government has zero influence on my chosen spiritual life.  

Demand for things like a return to school prayer is Demeaning of God.  When did Jesus, a human reflection of God, every ask for, or receive special treatment by a formal religious or government institutions?  God does not need our help.

I'm not sure this particular letter writer would impose his beliefs on others though.  

"We all need to be courteous, balanced and thoughtful in our conversations and curious about what others believe and why".

I can live with that.   Why create enemy's by alienating a Christian of good will?
