""That's not in itself about religious persecution, though of course there's no clear line to be drawn between these things.""
OK Kevin, one last try!
Is there anything other than the claims of organisations with a built in Christian bias, to prove that Christians are being persecuted because they are Christian, rather than because they are a minority and different than the majority?
If there is unbiased and factual evidence, has the same criterion been applied to minority sunni and shiite communities. I tend to doubt it.
