I have a number of relatives who are active in the UCC. They are not loony liberals, far from it. They are successful businessmen and women, respected tradesmen and they work tirelessly to help those who are in need. (I'm talking Guatemala, Haiti, Jamaica etc.) I've been to their services and I can say that most Protestants would feel pretty much at home. They are no more liberal than several other Protestant denominations like Lutherans (mine) and Presbyterians (the liberal branches, I'll grant you, but still the larger branches...)
I hate to see people making broad pronouncements about groups of people with no truth and no evidence to back it up. It's just not possible to have any sort of meaningful discussion. Pity.
So much hate, it makes me sad...
