@kritiper “That church is somebody’s name.”
And how many people are really aware of that? It seems like your issue here is how others might perceive it, so the general public, being largely unaware of the name of the founder of that establishment, could interpret Church’s Chicken as a place of worship and fast food.
And yes, I’m being somewhat intentionally absurd in citing Church’s Chicken, as I feel your complaint here is absurd. No one is going to mistake an organization of atheists for a prayer and worship group, even if they have “church” as part of the name. And given the apparent nature and purpose of this group, to provide congregational and ministerial services, the use of the word “church” is perfectly valid.
