Twitter and Scientology: Don't use the 'S'-word
When he walked past a Scientology centre on a trip to London last year, a councillor from Cardiff cannot have expected that his reaction would end up fuelling another big hoo-hah over free speech on the internet.
Nor that it would end up with him being hauled up in front of his council's ethics committee.
But Councillor John Dixon's mistake was to go on Twitter and say this:
"I didn't know the Scientologists had a church on Tottenham Court Road. Just hurried past in case the stupid rubs off."
Somehow this was spotted by a member of the organisation and in due course a complaint was made to the Ombudsman for Public Services in Wales.
The watchdog has partially upheld the complaint; to be more precise, it has found there is a case to answer under the code of conduct for councillors and has passed the matter on to Cardiff City Council's Standards and Ethics Committee.
So it seems Councillor Dixon has joined the growing list of politicians who have found that careless tweets can damage their careers. 1-0 to the Scientologists, then?
Not so fast. When news of the case erupted on Twitter this morning, it rapidly became a cause celebre - or rather a cause for mockery of Scientologisty.
Prominent members of the Twitterati - a crowd which includes many who are free-thinkers sceptical about religion in any form - started retweeting Councillor Dixon's original remark. Very rapidly, the term #stupidscientology became a trending topic on Twitter.
Now there are all sorts of lessons one could draw from this affair - about the dangers of social networking for politicians, the perils of taking on Twitter, the advisability of spending many hours and presumably a lot of public money investigating whether the word "stupid" is sufficiently offensive to constitute a breach of a code of conduct.
But, rather than face being hauled up in front of an ethics committee myself, I think I will allow you to draw your own conclusions.
