Here's an interesting example of this...

Last month the Saudi daily Al Riyadh published an article that accused Jews of consuming the blood of Christian and Muslim children during the holiday of Purim. The author, a lecturer at King Faisal University in Dammam, Saudi Arabia, called this medieval fiction a "well-established fact."

And yet when troll states the idea that Palestinians hate Jews more than they love their children, he states it as a well-established fact.

Can't see much of a difference myself.
