There is a reason why religion is not given total immunity from the laws of society. During almost fifteen centuries has the legal establishment of Christianity been on trial. The Constitution for the United States of America was not drafted overnight, and the religion clauses of the First Amendment are the result after numerous other proposed wordings were rejected. The words of the Constitution and of the religion clauses were debated and deliberately chosen. The Constitution, therefore, is not a blank piece of paper upon which we are to read whatever we choose.
Understanding is as simple as reading the words.
Yet, confusion obviously exists in comments from laymen to scholars, from clerics to justices, because of refusal to accept the words, as written, to say what they mean and mean what they say. I learned to read in a one room country school house in Kansas. I was taught that honest words mean what they say. In America, religion is to be freely exercised, not established or imposed by law or government. Words mean things.
