Why is it so common to blame religion for the world's woes?

I understand that many disputes, even wars, have been said to have existed due to religious differences, but historically there have been many other defined causes of wars, injustice and disputes. What about power, love or materialism? Many atrocities have been committed in the name of differences or ideologies.

Political or personal power has been cited as the cause for countless instances of violence. Land or resources are a very common source of bitter feuds and bloodshed. Or simply vengence over alleged (or actual) wrongs committed by the enemy. Sometimes it’s just because an individual or a group is “different”, that horrific injustices have been committed. Even the desire for a particular woman has, in the past, caused wars or bloodshed. I’m certain that astute and educated others could add to this list.

I have seldom or never heard anyone say “I am giving up land, oil or money because they have caused so much war and bloodshed.” Or politics and power. Or certainly not love or relationships.

I think that these are all excuses, and that all disputes are caused by human beings, their desires and their ability to hate, and not an ideology or an object.

Why the bias against religion? I think that humanity should decry, even aspire to stamp out, bias and hatred.
