Atheism is unstoppable.

Not all are fading, though. Whilst traditional Christian churches have shown massive declines in the 20th century, Islam shows a lot of growth in the last 20 years, which is a cause for concern.

Why do you think that is? I feel that Islam is less flexible that Christianity, so is resistant to dilution and probably retains better. But is the growth due to immigration? I find it hard to believe it is actually drawing a significant number of people in from the outside.

Not migration, more a combination of isolationism within society mixed with higher birth rates which serves to propagate the population. In addition I feel that Islam as an entity is more than just a belief, it’s a way of life trust informs everything from political decision making to social norms. At least in a way that Christianity used to but no longer does. What you say is, in my view, correct; there is little flexibility in most Islamic dogmas, though naturally depends on what Islam you follow. I remember a figure from a while back which indicated that a lot of new mosques here tend to be deobandi which is of concern.

Probably more nuanced than that but as a high level overview I don’t think it falls wide if the mark. I wouldn’t necessarily exclude migration as a contributing factor but I don’t know what the figures are so can’t say either way.
