The Dutch thought the Arabs would be the same. It didn’t happen that way and now many of the Indonesians are politically indistinguishable from Turks and arabs. The imams are, as here, largely sent and financed by Arabian Wahhabis ad that, naturally, has had an effect. France made a similar but much worse arrangement with the Algerians, most of whom were “nice people” fifty years ago and seemed to be assimilating at first.
Have never run into a bad Indonesian.
