And what exactly is a faith based business?  
Does the faith have to be Christian or can other denominations have the same justifications upheld by you.  
See I remember growing up in a very large community where if you did not speak Yiddish and attend the synagogue  you  could not buy Kosher goods at some shops; the Italians places  would not serve Jews nor would the Irish allow  anyone to move their neighborhood who was not of Irish decent.
