When we belonged to a Unitarian Universalist church, we used to joke in the parking lot that the more bumper stickers you had on your car, the more “religious” you were. The UUs really like their bumper stickers! (And they aren’t religious in the regular sense)

Unitarian Universalist or humanist sounds right up your alley as well Mr Nys Guy

Unitarian Universalist is the way to go, no doubt. You can be a proud atheist there too
