The lunacy continues.
I’ve heard atheists talk about why people like religion, and they sometimes fall upon the conclusion that it is the community.
Here are people who celebrate life milestones like births, deaths and marriages. They gather regularly for holidays / holy days, creating community and connections, something too few atheists have, hence their higher divorce and suicide rates. Rituals are reassuring, but they lack those of the Christian community, so they gather and sing their own songs. (”Imagine” is high on that list.)
The atheists attracted to these churches long for a larger community that many atheists only see in political organization, but that lacks emotional depth. Atheist churches are an attempt to bring deeper emotional connections and community to their lives, something churches naturally create unless too strict or abstract.
