An advertising campaign was to be run on TfL buses promoting a supposed 'Gay Cure' for Christians who wanted to be straight. The ad would have been worded "Not gay! Post-gay, ex-gay and proud. Get over it!" This was in response to Stonewalls recent bus campaign 'Some people are gay, get over it!'

The adverts were booked by the 'Core Issues Trust' whose leader, Mike Davidson, believes "homoerotic behaviour is sinful".

The terms 'Ex-gay' and 'post-gay' are often used by people who who believe in or have been through so called therapy which they claim can reduce feelings of same sex attraction.

Labour MP Chris Bryant said "The emotional damage that is done to the individuals who try to suppress their sexuality, the women they marry and the children they might have is immeasurable."

The advert was pulled by Boris Johnson a few hours after a front page story on The Guardian's website and an apparent storm of protest on Twitter.

Why would TfL allow such an advert to be placed on their buses in the first place? Perhaps the cited £10,000 had something to do with it.

Update

It would appear that TfL decided to ban the ad and then contacted Boris, rather than him initiating it as suggested in the Guardian article and elsewhere.
