Killing in the Name of...

Andrew Sullivan gets it right:

Imagine an Islamist fanatic had assassinated a pro-Israel rabbi in a synagogue, and had harassed synagogues for years, including one arrest for bomb materials in his car. Imagine if one of his associates had tried to kill the rabbi before. Would there be any question that this was Islamist terror? So why is this not Christianist terror?

By "this," Sullivan is referencing this (if you hadn't heard).
