If I want feminist humanism, I can turn on the TV or pick up any magazine at the supemarket checkout counter
My wife and I left the United Methodist Church behind in 1979, and have never looked back. We still go to Easter services with her folks, and it seems as though the typical congregant nowadays is 70 or more years old. It's kinda like the founder of Willow Creek Church. Once a year, he goes back to the church he grew up in -- just to remind himself of everything he wants to avoid!
One of my fantasies is to buy an old UMC church building some day, move in, and start a living church within that shell. It's not impossible -- some Pentecostal friends of mine were once GIVEN a beautiful old Unitarian clubhouse, since the members were all dying out!
