Whilst I am on the opposite side of the marriage debate debate to His Grace, I am vehemently opposed to the actions of those who have complained about him carrying an advert (show below) by the Coalition for Marriage on his blog.
The UK is, supposedly, a democratic, civilised country and in such a country the freedom to express opinions which others might not disagree with should be an inalienable right.
Complaining about someone who has a different opinion to you – and expecting it to be followed up – is an action which Erich Mielke would be proud of.
If the Advertising Standards Authority had any common sense whatsoever it would have gone to the source of the advert, found out what the information used within it is based upon and told the complainants to go and play in the traffic.
Instead they went and harassed a blogger about it. If I were His Grace my reply would be, as others have already suggested, along the lines of Arkell v. Pressdram.
