No, the Seljuk Turks were destroying Christian hily places and antiquities before the Crusades. That catastrophe is one of the reason the Crusades were called for: to defend the Christian communities of the Middle East: their churches and shrines, their properties, and their people.
The Crusades were no more "aggressive" than the landing of Allied troops at Normandy.
