It may not be persecution exactly

but it is most certainly harassment and intimidation and an outrageous attack on free speech.
Someone has complained to the Advertising Standards Authority  about the Archbishop Cranmer blog running an ad for the Coaltion for Marriage, something which which the complainants allege is discriminatory and (wait for it) 'homophobic.' 
See here for the full story of the subsequent inquisition.

This is a flavour of Cranmer's reply: 

"....His Grace is further minded to respond that he has neither fear of nor hatred for the gay and lesbian community, though he is a little pissed off with 10 of them. They could easily have emailed His Grace with their complaint, and we could all have had a jolly good chinwag about the whole thing. Instead, they called in the Gestapo to censor the assertion that marriage is a life-long union between one man and one woman, in accordance with the teaching of the Established Church, the beliefs of its Supreme Governor, and the law of the land.
But to say so is now, apparently, ‘offensive and homophobic’.
Well, His Grace won’t be censored. He is further minded to provide the ASA with a copy of his well-publicised ‘bottom line’ (from the right-hand margin):
Freedom of speech must be tolerated, and everyone living in the United Kingdom must accept that they may be insulted about their own beliefs, or indeed be offended, and that is something which they must simply endure, not least because some suffer fates far worse...
Unless, of course, we are no longer free, our democracy is no longer liberal, and it is now an offence to express the moderate view of the majority and promote the orthodox teaching of the Church of England Established..."

And here is the link to  C4M  so you may judge for yourselves.
Although, on second thoughts, whatever we might think of the advertisement itself, perhaps in solidarity we should all run it, purely in defence of our hard won civil liberties and the teachings of the Church.
