For a collection of posts on Purim see here.  These deal with topics as diverse as Jewish humor and parodies, a series on the the origins of hamantaschen (and here and here), banging at the mention of Haman’s name, piyutim for Purim, mishcholot manot, identifying the personalities of Megliat Ester in secular sources, how to approach the story of Ester with children by the late Elliot Horowitz, as well as a couple posts regarding his book on Jewish violence and Purim, and mixed dancing on Purim.
