I assume you're referring to the fact that it's just a "made up" church? [1] Some of the most fanatical church go-ers that I know of are C of E. Of course, that could be my limited experience.

I can see how in the US it can be hard to be an atheist, but as an atheist in the UK it can be a minefield too. Just sat in the pub having a discussion the other day with some people I've known for a while and they were shocked when they discovered I was an atheist and tried to go down the whole, "how can you not believe" yawn and started to get quite angry. I've had that a couple of times now and had to extricate myself with, "look, I can take you through my many years of thought that brought me to this conclusion that will have you seriously doubting your faith, or we can just accept that we both have different opinions."
