Go into any airport bookshop and you'll see that honour killing sells. Bestseller after wannabe bestseller illustrates the template -- the cover photograph of a woman peering out from behind an attractively draped scarf, the exotic setting, the Romeo-and-Juliet storyline. It's a crowded field, so you can see why the Festival of Dangerous Ideas a) wanted to cash in, and b) felt the need to differentiate its "honour" killing event in an overcrowded field by casting a wild-eyed man rather than a doe-eyed woman in the lead role. I'm prepared to believe that it takes a lot to jolt the FODI's target audience from their carefully cultivated ennui, but the session with the title “Honour Killings Are Morally Justified” featuring Hizb ut-Tahrir spokesman Uthman Badar clearly set the voltage too high.
