Don,
His agenda is invariably to denigrate Muslims as a group,

That is simply not true.
I have never done that.
I have put Israel's case at times when no-one else did, and I have challenged the veracity of some anti-Israel propaganda.

Greg, you have expressed certainty.
I never have.
I have just said, "You think it "bullshit" and you might be right."

I have put up evidence, not proof.
The Vatican statement, and the reports and research behind it, has not been challenged even by the many enemies of the Church.
The Guardian, which finds space to report the antics of a few hillbillies, found no-one to accuse the Pope of bearing false witness.
So I ask you again Greg.
How do you KNOW that the research is flawed?
How can you be CERTAIN it is not, possibly, true?
