Terrorism isn't confined to Islam, but if you look it up on Wikipedia it seems a large percentage of it is committed by muslims.

It's not so much Islam being the problem but the worship of books, any zealot can interpret a book to mean whatever they want if they have an agenda.

Catholics have crusades ( yes they still have them google the black pope or jesuits and war) and Islam wants a caliphate. it's all about power. The people dying and being killed are just pawns in the game or collateral damage that the hierarchy of both systems seems to think is acceptable.
