Tomorrow evening Channel 4's Dispatches programme will show women preachers at London's Regent's Park Mosque urging followers to kill homosexuals.
The programme is a follow-up to the Dispatches on Undercover Mosques.
In this new documentary, a female reporter infiltrated women’s study circles. In one, a preacher using the name Umm Amira tells followers: “We are not going to be like animals . . . or to be like the homosexuals, God save us from that, you understand? We have to take the judgment, the judgment is to kill them.”
There is only one single valid response to this. They should be prosecuted for incitement to murder.
It would be tempting to dismiss these calls as the ravings of a lunatic fringe.
So it is important to point out that last year a wide-ranging survey of Muslim opinion showed that 71% - yes, 71% - of young Muslim men (aged between 16-24) thought that homosexuality should be illegal.
I hope that the gay community wakes up a little, so far as this issue is concerned.
I am sometimes exasperated, as a gay man, by the lack of reaction from the gay community to incitement of the kind above, or indeed to the uninhibited hostility of a large section of the population.
Many gay men still think that civil partnerships and adoption are the big issues. Islamic hostility doesn't affect many of them as yet. But it surely will.
