I do cringe at the media referring to Sunday Assembly as "atheist church" because those two words shouldn't be in the same sentence. If anything, it's secular humanist, not merely atheist. Regardless...
This is exactly what I'm talking about. I already signed up to try and get it in DC.
"Sunday Assembly" - we used to call it "Pub". It followed a game of "Footy" in the park.
.... but that was before we made the interwebs, the land time can't remember.
