Barham Salih [the Iraqi minister who said mosques in Blackburn are more radical than those in Iraq] is a Kurd, and likely to be less fervent in his faith than those who, as Arabs, have an identity that reinforces rather than undercuts or provides an alternative to, the identity provided by Islam. He cannot, in Iraq, speak out openly about what he might call or choose to believe is "extremism" in the mosques --nowadays, that means mostly Shi'a "extremism" -- but he can visit mosques elsewhere, and his comments, also contain an element of oblique comment on the situation in Iraq.
Since, at this point, aside from Al Qaeda in Iraq, many of the old Sunni (and Ba'athist) elite are worried about the new power of the primitive Shi'a masses, shown in the forcible re-covering of women in Basra and the entire south, and those Sunnis who were used to the relative "secularism" of the Ba'athists, now recognizing the broad attack on the previous "secularism" (that Saddam Hussein had ruthlessly enforced, not because he was in any way against Islam or a free-thinker, but because he recognized that in Iraq, any Islam-based threat to his regime would come from mosques, and those mosques would be Shi'a, not Sunni), worry about, and despise, those primitive Shi'a masses and their leaders, those whom those secular Sunnis, and of course the Christians in exile, denounce as "the turbans" (which clearly means "the Shi'a" who, unlike Allawi or Chalabi, take their religion most seriously).
The comment of Barham Salih about the "extremism" of the mosque he visited in England is perfectly, uncomplicatedly truthful. But what led him to make the comment reflects his own position, and views, and background, and the current state of affairs in Iraq, where the Shi'a have won, and now, within the Shi'a camp, the fight is between the "turbans" and the others, the ones whom so many in Washington assumed, quite naively, would necessarily inherit power -- Chalabi, or Allawi, or others of that secularisant ilk.
