As an atheist this does offend me. Yes I regard it as fiction, however it is extremely dangerous fiction, and establishing a tolerance for it to be favored over another group is a slippery slope.

Religions have been used as tools to suppress dissent, stifle debate, control the people, and ultimately, to take away people's rights. Look at the christian-right in our own government that decries gay marriage and abortion on religious grounds. That is the type of influence that ordinances like this give to religions.

Church and State are separate in this country for a number of reasons. Government exists to carry out the will of the people, ALL the people together, not the will of one religious sect. The will of the people is for government to do its job, and as "ACfH" pointed out, this is a distraction from the assembly doing it's job.
