While I don't mind the fact that they're trying to make the census more accurate (which is a good thing), it's for an ulterior motive. Which is not a good thing.
That's from their website. How paranoid do you have to be to assume that religious institutions are going to use a joke religion to get money? Saying stuff like that only makes people turn against you.Any other response may be manipulated into a response in favour of religion and publically funded religious organisations.
