To me it seems like calling that the fault of "religion" seems roughly analogous to blaming the concept of "government" for the actions of a specific city or state/province government? (that is, either 1 or 2 levels below a national government , though I might have made a mistake with the analogy there)
Not all religions/versions of a religion are the same.
I acknowledge that an analogy is not always a particularly strong argument, but it was the first responce I thought of, and it seemed an acceptable responce to me.
Also, it might have made more sense to respond a few levels up, not sure what would have made the most sense to reply to.
