religious wars don't happen because of religion, but that religion is hijacked as an excuse to carry out what are essentially economic goals.
1) does this fundie suggest that reigion never does violence in the cause of religion? or just not wholesale wars?
Because the Inquisition(s) targeted not just the rich, but every "heretic", every Jew who had converted and who they thought was secretly practising Judaism, whether they had wealth or not. Similarly witch trials/execution in Europe and the US didn't target only wealthy people, but anyone that the religious fervor pointed toward. The horrors of torture and imprisonment extended to children as young as 7 years old.
The Church's genocide of the Cathars didn't spare the poor or landless. As that Archbishop said: "Kill them all, God will know his own."
2) Even if one wants to say the Pope's engineered the Crusades in order to gain property and wealth (which I will admit would be "part" of the impedus for war), the realty is they wouldn't have rallied armies of hundreds of thousands of people and march them across a continent without participation being enflamed by appeals to religious righteousness/ justification.
In other words, religion was a catalyst, and religious people thus killed for Christ,
irrespective of what the Nobels, Kings, and Popes ultimate goals were. Without religion as a basis for action the call to war would not have prompted a large enough response to field such armies. If it had, they wouldn't have had to appeal to the religious side of people
So to suggest that religion didn't "cause" war, is to misunderstand or ignore the power that the appeal to supernaturalism, and dogma has to rally the theistically impaired. And that's all it takes for religion to bear the brunt of the cause of many wars.
