I agree Jack, my experience is limited to W African Muslims. And my husband is Sunni. And I have found that animism is alive and well in Africa, despite the efforts of imams and Christian leaders to stamp it out.
Regarding Catholicism in Ireland, my mother was a Catholic from Cork and was subjected to exactly that sort of repressive control by the priest. On coming to England, she promptly joined the CofE and never looked back.
But the initial post was concerned only with the UK. My point was that while Christianity is diminishing here, Muslims are flourishing and some sorts are actively recruiting young folk to their cause, which is maybe emphasised by the Government video for all school staff warning about it.
As an aside, I have always found blooming teeth to be a major design fault in the human body. Several of mine are loose, and no doubt I shall need dentures shortly. I wonder if an update (like Windows 10) could be engineered, with no uteri, teeth, bottoms, joints or digestive tracts. These seem to be the parts that cause most trouble.
