For a while my niece was attending a Unitarian Church. She liked it for a while but eventually the church became divided because the minister was talking about God (or god) too much. Some members (who were atheists) were really upset.
Everyone liked the songs and the fellowship, but not God. My niece also mentioned that at one of the church group meetings they couldn’t figure out why they kept losing members especially since their church was so “open”. It was hard for me not to laugh when my niece discussed her concerns with me.
I once heard the phrase, which I often use now - "they're so open-minded, their brains have fallen out."
