cultural appropriation

What Jarred said about cultural appropriation got me thinking. So did the 'holding the bread too high at Communion' thing.
So is holding the bread up high (to at least face height) during Communion simply an irrelevance about which no-one in their right mind should be bothered? Or is it an example of an act which can be perceived as misplaced cultural appropriation?
If I go to a Catholic Mass, I expect the priest to hold the wafer up, the bell gets rung, and the theology is that at this moment the bread actually becomes the body of Christ. I personally may or may not believe this, but it's what I would expect.
In a denomination which has very much the view that 'the bread stays bread' and Communion is purely an act of obedience and remembrance, anyone can lead the service and break the bread.
So, in this setting, anything which carries overtones of (1) needing a priest (2) the priest offering a sacrifice (3) the bread becoming Jesus' actual body is seen as inappropriate.

Personally, I don't care - I've had communion with wafers, brown bread, white bread, teacake (bread with raisins in), poppy seed bread; wine, grape juice, Schloer, cranberry juice, raspberry juice, Ribena/other blackcurrant juice, non-alcoholic wine (which has the scary label "Not to be drunk as a beverage"!). I think the most moving communion I had was as part of a small group and we used crisps and Coke, because that was what we had.
But I do have to admit that seeing the bread lifted high in that particular church service jarred.
So is that inappropriate cultural misappropriation? Or just tradition?
