If its bad here in the US, it has to be worse in the UK.
Actually, from all I've read it's at its worst here in the US. They're still arguing over whether to have women bishops, whereas the first woman bishop in the US was ca 1990 as I recall (and had no pastoral experience, was heavily underqualified -- but she was female and black). They've also been providing alternative oversight for priests who will not tolerate their liberal bishops -- "flying bishops," they're called there.
The one thing possibly worse there is the low attendance. And one bad thing they have that we don't is the state-church tie, which is being used to force more liberalism down their throats.
But all in all, it is the Episcopal church in the U.S. that's driving this madness.
