Atheist Marriage

Some Atheists have come to such a narrow view of religion that they can not see that even an atheist puts a lot of faith in something. An Atheists religious paradox is not the state's parameter because of an Athiest's own narrow sense of religion. I question why an Atheist gets married at all. do Atheists have faith in marriage? the words and semiotics of "Atheist" or just "not religious" still take faith in those concepts. What an irony that an atheist insists on meaning at all.
