Discrimination and persecution overlap, but they aren't the same thing. And they can both cover a wide range of things.

The evidence does seem to indicate that when it comes to people being in danger of death by reason of their religion, that's more likely to happen in the case of people belonging to minority Christian communities than to other religious minorities at this time in history. But I hold by my view that league tables about such things are irrelevant.

Typically this type of persecution tends not to be about people being targeted because of their religious beliefs, but because they belong to a rejected minority.
