Mechanics matters.
If the only difference between onesubrace ofElf and an other is Perception versus Arcana, or longbow versus handbow, that would come across as racism. As if an other culture is a separate species.
I feel confident a setting based concept with a new name can be found which doesn't smack of racism and requires zero tweaks to mechanics. Someone mentioned earlier the concept isn't about biology and is more about magic and the Gods of the setting and I wondered if that was maybe the issue at play here given your take on default concepts of religion in D&D.
