I believe that all faiths should continuously, and without ceasing, "have it out" in the arena of ideas -- in philosophical debate -- but MOSTLY in the arena of proof by good works. The superior philosophical and religious ideas should thus win the day, and the ideas of least value to society and humanity should fade into deepest night -- a good teaching of history from generation to generation to keep them forever there.

That is one good reason (to my way of thinking) that no religion should ever be backed by the power of any government. Religious ideas should not fall back on the weaker philosophy of "might makes right". We know that maxim is not true. We seem to continually have to re-teach ourselves that lesson.
