It's hard to argue with bits such as:
What I think may be abuse is labeling children with religious labels like Catholic child and Muslim child. I find it very odd that in our civilization we're quite happy to speak of a Catholic child that is 4 years old or a Muslim of child that is 4, when these children are much too young to know what they think about the cosmos, life and morality. We wouldn't dream of speaking of a Keynesian child or a Marxist child. And yet, for some reason we make a privileged exception of religion. And, by the way, I think it would also be abuse to talk about an atheist child...
When a Protestant murders a Catholic or a Catholic murders a Protestant, they're not playing out doctrinal disagreements about transubstantiation.
What is going on is more like a vendetta. It was one of their lot's grandfathers who killed one of our lot's grandfathers, and so we're getting our revenge. The "their lot" and "our lot" is only defined by religion. In other parts of the world it might be defined by color, or by language, but in so many parts of the world it isn't, it's defined by religion. That's true of the conflicts among Croats and the Serbs and Bosnians -- that's all about religion as labels.
The grotesque massacres in India at the time of partition were between Hindus and Muslims. There was nothing else to distinguish them, they were racially the same. They only identified themselves as "us" and the others as "them" by the fact that some of them were Hindus and some of them were Muslims. That's what the Kashmir dispute is all about. So, yes, I would defend the view that religion is an extremely potent label for hostility. That has always been true and it continues to be true to this day.
