I have a low attention span but I read through your entire document and when I reached the end I was surprised because I had the impression I was still reading the preliminary part. So, for what it's worth, I found it easy to get through.
That's a good sign. Thank you for your donation of time and effort!
Edited 3/4/2012: I shortened up the summary a bit and add the following update:
Thanks for the lively comments. As a preliminary summary of things I've found quite useful/helpful:
It's almost one year later, and I've finally made tangible progress on some of the input suggested in my post about being non-religious in a primarily religious environment. That is, I have a near-final draft of a "coming out" statement I plan to share with a majority of those who know me.
I was involved in two religious communities for about six years of my life (SPO and CCR). Two years post-deconversion from Catholicism, many of them still do not know I no longer believe in god. This can make for awkward interactions for myself, as well as for my wife, who's still a believer. She thought it would be helpful if everyone was on the same page, as did I.
