The point for me is recognising that Western evangelism is evangelical in nature, and not - let's say - diplomatically persuasive.

And of course I mean capitalist evangelism, with its emphasis on buying, selling, and organised work as perfectible social aims, and competitive profit as the ultimate personal sacrament.

The rest of Western culture - the literature, music and the rest - is a side-show in comparison.

So is Islam, because evangelically there is no such thing, just as there is no such thing as Christianity. Instead, there are hundreds of competing sects, denominations, and value systems, many of which disagree with each other, sometimes violently.

Capitalist evangelism is comparatively uniform, and far more politically and culturally influential. It also squares neatly with the oligarchical political structures of supposedly religious states like Saudi Arabia, and of supposedly hostile states such as China and Russia.
