Saudi Arabia’s King Abdullah is visiting the UK. Yesterday we noted that King Abdullah chided the British for not doing enough to fight terrorism. We also noted several reasons why no Saudi ought to criticize anyone else for a substellar anti-terror effort. Here’s one more reason the King should’ve kept his opinions to himself.

Extremist literature that encourages hatred of gays, Christians and Jews can be easily found at many of Britain’s mosques, according to a new survey.

Researchers for the centre-Right think tank Policy Exchange claims it found the literature in a quarter of the 100 mosques and Islamic institutions they visited.

Many of the publications allegedly called on British Muslims to segregate themselves from non-Muslims and for unbelievers to be treated as second-class citizens wherever possible.

The literature also allegedly contained repeated calls for gays to be thrown from mountains and tall buildings and for women to be subjugated.

Policy Exchange said that among the documents were the anti-Semitic forgery, The Protocols of the Learned Elders of Zion, and other publications peddling bizarre conspiracy theories.

That’s not much of a surprise; they don’t call London “Londonistan” for nothing. But the fact is, this isn’t nearly enough of a surprise either.

These aren’t fringe or fly-by-night mosques; the British Royal Family has visited several of them. The literature involved is unfortunately all too familiar to anyone who has spent any time looking into jihadist propaganda.

The report singles out the Muslim Council of Britain for criticism, as the MCB is linked to several of the mosques that distribute this literature. Predictably, the MCB’s response is to try to turn the criticism back on its critics.

Iqbal Sacranie, a former secretary general of the Muslim Council of Great Britain, criticised the report. He said: “The majority of Muslims will totally dismiss this because it is written by the Policy Exchange, who have an agenda to denigrate the mainstream of Islam in this country.

“If there is any material which falls foul of the law, then the law should take its course. We cannot accept messages of hate – there is zero tolerance on that. But it is irresponsible to target religious texts and take them out of context. These texts can be found not just in mosques but in ordinary bookshops – the report overlooks that.”

These mosques are giving away for free what people can buy in a book store — that’s not much of a defense. In fact, it’s more of an admission that there’s a widespread problem.
