Sounds very familiar to me. If I want to do volunteer work, the best organised charities are religious. Maybe atheists should establish a rival to St. Vincent de Paul. I attend church with my wife who is a believer and my stepson who is a non-believer and have done a lot of volunteer work with a lot of good people in the religious community. I don't enjoy the anti-gay marriage or anti-abortion ads, but it's not all bad.
As far as atheist community goes, there is an atheist meetup group in my area that I went to early in my days of non-belief but I found it very disenchanting to sit around and bash religion all day. If that's what some people want to do that's fine, but it's not what I want to do. Hey, I'll bash religion myself in some contexts. Atheists who claim the high moral ground in regard to rationality are often very irrational in their critique of religion, and often have a skewed view of religion and its effects on people's behaviour. It's good to hear an atheist who thinks differently. There are others out there too, but their voices are drowned out by the empty atheist vessels making the most sound.
I'm not saying that there isn't a place for the Ditchkinses of the world, but I don't think it's right to undermine someone's belief system without giving them something meaningful to replace it with. The suggestions of some atheists about a meaningful life are just glib and superficial, not to mention unrealistic. A prime example is Michael Shermer who describes how life can still be beautiful without God, citing the example of his getting married in Chartres Cathedral. How many people can afford to get married in Chartres Cathedral?
