You're right, especially about the cynicism. If I understand correctly, the Unitarian Church is for people who have to belong to a church to be upstanding members of the community, but don't really believe in anything.
The Episcopalians are becoming the same thing.
BTW, I used to have an Episcopalian friend who referred to himself as a Whiskeypalian.
My brother visited one and had to hurridly leave, lest he disrupt the (travesty) of a service by losing self-control and laughing out loud. Some speaker was offering a weird mixture of imported Eastern philosophy, contemporary CorrectThink ™, etc.- The "G-d Optional" stuff.
