"And when you mock the heritage of a people in this way, it is a prelude to trivializing what is most important and diluting or dissolving identity."
Mansaf is a rice-and-mutton dish traditionally eaten from a large, shared platter using one's bare hand. We're told "Often, the sheep’s head is placed at the center of the platter. Its cheeks, eyes, brain and tongue are highly prized and intended for the table’s most important guest."
Perhaps the traditional style of eating is more important than the food itself, but does that mean you shouldn't eat the food without the traditional behavior, that it's a mockery to eat it in some other way? I can see why you might want to deprive people of the food unless they follow the tradition, because that would cause people who crave the food to slow down, gather together, and interact with each other. But it's hard to understand that eating the food — with a spoon — from a paper cup is mockery.
The only thing I could think of is if someone were to sell communion wafers for people to snack on like a roll of Necco wafers.
