"However it is categorically not simply a members club that you can boycott. Non-catholics and catholics of the pick and choose mentality may rail against this concept until the cows come home but that is the reality. Fact. No amount of argument is going to change that reality."
It's not a fact though. I, and many like me, were good (ie loyal) catholics until they lost their faith. It IS a choice, to imply otherwise presents faith as a matter of fact when, by its very definition, it is in fact the polar opposite.
"I objected to the word "club" because I think it trivialises (I don't mean that rudely btw) it for me. It is bound up with my life in a way that no club could be. IT's not like the WI or something. I am a catholic culturally as well as in faith."
But that was rather the point I was highlighting. Catholicism as culture is precisely what Dawkins wasdriving at with his pithy observation regarding the chosen faith of children of te faithful.
It IS a big club; it's a club that you may choose to join (or your parents may choose for you) and you are free to leave at any point. It's not something inavoidable, like being a specific colour or being born in a specific country, and its only unifyuing factor is that, once you've joined, you call yourself a member of the club.
I love the line about not being like the WI: have you ever seen a gathering of priests for a weekend together?? 
I grew up around, with, alongside priests, nuns, religious types of all kinds (although largely and through the aegis of catholics; I went to church virtually every day; I truly know what it means to be a catholic through culture as well as/rather than via the vehicle of faith. I'm not treating it lightly when I compare it to a club; witness the fierce loyalty your average Newcastle United fan displays! And I certainly don't mean to offend you, seeing as you're cearly gracious enough to reply to my (often potentially flippant) posts with good grace.
