I think you're misunderstanding the other side.
The pastafarians are making fun of religion, but more importantly, they're making fun of how accommodating we are of certain religions, while ignoring others, and at our peril. By fighting for their right to wear a pasta strainer in an official photo (mocking religions with headgear... which I'm guessing yours isn't) they're pushing us to re-evaluate our habit of accommodating increasingly idiotic religious viewpoints.
Pastafarians don't want to wear a pasta strainer, they just want to live in a world where this doesn't happen.
The state needs to be secular, and it needs to have the spine to say, "no, fuck you" when somebody else wants it to
not be.
