I really don’t care what they are called except that they are not called altars. For some reason, it is a my pet peeve of mine. Probably unjustified pet peeve, but it just seems to me that wording associated with the mass should be used very carefully in other contexts. It also seems to perhaps, unintentionally I admit, downplay the fact that the mass is a sacrifice. If anything can be called an altar, than the word is not associated with sacrifice, then perhaps the fact that it is called an altar in church has no significance. Finally, when I hear the word altar used in this context, I can’t help thinking that these people just don’t get the significance of an altar in the church. I know, its a stretch, just trying to justify my pet peeve.
