It's not only the gains that they fought for, the Christians were fighting, especially in the First Crusade, to defend what they already had, which they thought was being threatened.
Going to war is a judgment that leaders make, regardless if their decision is a good one or not. The judgment was made to go to war to protect and further financial interests.

Okay, but this does not make your point that religion is not religious. Take a look at my earlier response to your argument.
With respect to the Crusades, recall that one example or even a thousand examples of the misuse of religion do not in any way make the argument that religion is not religious. These examples do show that sometimes religion can be used in nonreligious ways, but this is quite different from your thesis.

They still pray in similar fashions, still have mass at specific times, still follow a doctrine of faith based on the same original understanding of the same diety. By all rational accounts, they worship the same god.
No, the God is not the same. Again, the various faiths have different theological understandings of their deities. Even among Christians (or any other of these three monotheisms) we can find more than one notion of God - that is, we can find Christians worshiping Gods which are, theologically, incompatible with one another. For some, God is loving, for others God is vengeful, for still others God is both loving and vengeful.
I agree that they are ultimately trying to point toward the same thing, but this does not mean that the Gods being worship are the same.
For example, are Indra and Zeus the same God? The obvious answer is no, despite the fact that they both cast lightning bolts. Why are they different? Well, Zeus evolved out of Indra, and this evolution means that Zeus sheds some Indra-like qualities and adopts some non-Indra like qualities. Similarly, the God of Islam is not the same as the God of Christianity - both evolved from the same source, but in the process of this evolution these Gods became distinct deities with their own rites of worship, their own scripture and their own theological notions.
