On the other hand, I feel can discuss the subject with Silly Bugger.
First, I agree entirely that faith schools are a bad idea. That's because they encourage one-track thinking. One sort of faith is right and the others are mistaken, which is divisive, like putting your opponents to the sword.
The man in the sky, the old chap with a long beard and a black cloak peeking from behind the clouds, is an attempt to make us mind our behaviour on the basis that authority is watching us. That's Big Brother even before TV was invented.
As for the laws, they too are, in my view, an attempt to get people to behave. Religious laws go back to prehistory, no doubt, which is why civilisations had many gods, one for each sort of quandary. According to early history, however, the one God (which is what people here are thinking of) was the invention of a tribal leader in his tent some four thousand years ago. His idea is the basis of all Abrahamic faiths, which served us well for all those millennia, so long as you're not a student of a faith (cf. sectarian) school and can't fly a jet 'plane into a World Trade Centre tower, or strap yourself or your children with explosives and nails and put them on a bus to Tel Aviv. Or occupy the Holy Land in the name of the Pope. Whatever.
What the one God fulfils, like His predecessors, is a space in our extraordinary minds for spirituality. You can fill it with other stuff if you want, but please don't let that stuff be theft or fraud or murder or sex with little children.
Some people here may say that they don't need a god in order to behave. I'd ask them, where did you get the idea of behaviour?
What's the point of all this here at NewsBiscuit? Well, if you can make a bloody good joke about it and post it in the Writers' Room, I'll give it stars.
