Let's take one example: 99% of Afghans think that the punishment for apostasy should be death.

That number struck me as surprisingly high, so I went looking for the source and I think it's this. The 99% number is for "Muslims who favor making Islamic law the official law" in Afghanistan. The death-for-apostasy proportion is actually only 79% for pro-sharia Afghan Muslims (which is still 79% too high, but isn't 99%).
