On the old site, there was a thread about things you had come to realise you had previously completely misunderstood and so I thought I would revive that here.
There is a great podcast called Throughline on NPR that will probably reveal a lot of cases of this for a lot of people https://www.npr.org/podcasts/510333/throughline
There was an episode recently on the role of Saudi Arabia in spreading a militant, puritanical version of Islam. I dont think that would be a shock to many people, but my perception of this had always been that this was a problem from the very founding of the Kingdom. My understanding, which I’m sure was shared by most, was that while the rejection of intellectualism in Islam took hold under the ottomans, it was the new found wealth of the new kingdom, one that followed a particular strange strain of Islam, that really caused it. They took advantage of the void in islamic leadership that the fall of the Ottoman Empire created and filled it with their strain, bankrolled by oil money. This episode painted a completely different picture. They present Saudi Arabia as being a fairly liberal place until 1979, when the grand mosque in mecca was held hostage by a fringe group. Their story was that it was only after that event, and as a result of the actions the Kingdom took to end the siege that emboldened the extremists and gave them the platform to start spreading their version of Islam.
