Both you and I know this is provocation, so there's no point in pretending otherwise. But sure, it is an argument in favor of the confessional state. Liberal societies are de facto confessional states anyway, it's just that the liberal religion (which Rawls can't quite seem to acknowledge as one, but deploys without scruples) by which all others are measured and restricted is not named as one.

I up voted your comment...

No because pastafarianism is a funny, if aged, joke among atheists. You don't sincerely believe in the spaghetti monster, and the courts could hold you in contempt.

But why would an atheist who likes to mock religion want to live in a country that criminalizes it?
