If I ever discard the mutant remnants of my christian faith, abjure my God and admit to the world "Yes, you were right, I've been following a stupid fairy story and what's more I knew that all along, I'm so sorry I wasted your time with it and incidentally I take full personal responsibility for such atrocities as the Inquisition, the Crusades and Godspell..."
...it won't be because of a realisation that the Bible doesn't describe scientific fact, because that's very, very obvious and I assimilated it into my faith a long, long time ago. It won't be due to the fact that textual transmission simply doesn't allow for the Bible to be the inspired Word of God in any consistent sense, because although I came to this realisation a fair while later, it was still a good decade ago, and my faith appears to have evolved to fit the modified mental niche that it created. It won't be thanks to a fear that by professing a moderate christianity I'm somehow empowering those who profess more dogmatic, fundamentalist and oppressive forms of the faith, because it's obvious to me that pulling out and abandoning Jesus' legacy to such people would empower them far more.
No, if I ever do apostasise myself it'll be because I'm so bloody tired of being stuck in the middle between the aforesaid extremists who make absurd politically motivated claims in my name, and the mostly reasonable atheists and agnostics who think it's fair to look at the behaviour of said extremists and tar the rest of us with a brush of idiocy.
Consider the first letter here, for example. In it, some men who hold unelected seats in the upper chamber of the national legislature by virtue of their position in the hierarchy of the state-established church sponsored by the monarch, complain that society discriminates against them because of their faith. I'm aware that Anglican bishops aren't usually the kind who come to mind when talking of the lunatic fringe, but note that slily casual reference to "Christian beliefs on marriage, conscience and worship" -- they're talking about their "right" to institutionalised homophobia.
You might think christians would be reconciled to powerlessness, given how the faith started, but 2,000 years of history have had their effect. In the minds of some, it seems that any erosion of the traditional power of christian authority to dictate the lives of others counts as persecution, however ludicrous this may look to outsiders. (Jonathan Bartley of Ekklesia has described the historical and political basis of this far better than I can.)
Those outsiders, of course, then think it's reasonable to make comments along the lines of "Not so nice when the bigot-boot's on the other foot, is it, Jesus-boy, eh? Eh? Ah!" and "Goodness me, what a lot of silly people these christians obviously are." Which, for those moderate christians who can entirely see their point but would rather not be poked with it ourselves, is terribly wearying.
(The less moderate atheists and agnostics are less moderate in their responses, of course. This can be hurtful and annoying, but there's still a gap between "hurtful and annoying comments which nobody makes much of a fuss about" and "culturally sanctioned persecution" which many of the christians in the early Roman Empire or the People's Republic of China would be able to help us explore.)
Certain parts of mainstream culture in the UK are all too happy to pounce on any possible instance of anti-christian "discrimination", while studiously ignoring discrimination against other faiths (or worse, portraying other faith groups' calls for inclusion as being themselves a form of anti-christian persecution). It's all too easy to add the words "...in our own country" onto the end of such complains, thus playing directly into the hands of the BNP.
In the end, churches in the UK are rarely the targets of hate crimes, unlike the mosques, synagogues and gurdwaras which the aforementioned BNP target. (When they are it's either due to long-held sectarian divisions within christianity itself, or because some psycho parishioner has a grudge against the vicar.)
Until I see a smoke-damaged church with "XTIANS OUT 666" scrawled on it, I'll feel that these bishops, and other christians giving voice to this kind of politically naive and damaging rhetoric, lack a basic sense of proportion.
