Why is it appropriate for the whole apparatus of government to be turned towards expressing one individual's (or even a group of individuals') beliefs? If they want to express those things, they can do it on their own time. The government shouldn't be expressing anything, since the government has no religious beliefs to express. Just because someone occupies an appointed or elective office, it doesn't become their personal fiefdom. For those of us who have moved out of the Middle Ages, there is a difference between an office and the office-holder of the moment.
