Bullshit. He plainly said *these* things are good so I'll give religion credit for those, but with *these other things* (which were bad but also done in the name of religion) I'll baselessly assert that the perpetrators weren't "True Believers" so religion can't be blamed.
I understand your logical argument, and I don't entirely disagree, but I can understand the position from which the other poster is coming. If, I, an agnostic/atheist were to pick up a Bible, grab 5 of my friends, and head off slaughtering people while shouting scripture, would that be a violent rampage of religion, or simply something done in the name of religion? I do not at all disagree that many bad things have come of improperly followed religion (As DrP pointed out), but it's just not that simple. Take the violence being carried out in Afghanistan/Iraq in the name of Freedom, Democracy, et al. Does this violence mean that Freedom/Democracy are belief systems which inherently bring about bad things? Of course not. There have been many beliefs that have driven people to violence, but it doesn't mean that beliefs themselves are to blame.
