Aiman Ayan (if that is his real name -- his Twitter handle is Aiman1979) wants Saudi writer Hamza Kashgari executed for blasphemy. When Muslim anti-jihadist Tarek Fatah steps into the conversation on Twitter, Aiman implies he deserves to share Kashgari's fate, too.

Watch the drama play out in the screenshots. It's a pretty typical run-in between an Islamist fanatic and a moderate Muslim intellectual. Fatah's best line: "@Aiman1979 U disgrace The Quran by asking for the death of a human being in the name of Islam. Who gave U that right? The Merciful?"
