Webeter says terrorism is coersion through terror. The type of terror is not specified and I don't think think it has to be, if you frighten someone to the point of terror to bend them to your will then you are a terrorist. By that definition, perhaps some catholic educators have beeen terrorist? I wouldn't know. But that is not what missionaries do. Perhaps a small number have used terror as a technique. But most use bribery ("Listen to me and I'll give your village medical care or water") or they just set a good example and preach. It has been an interesting discussion, but certianly the answer to the original question is "No".
