This feels like a fantasy equivalent of racial fetishization (which is generally considered to be racism), but it's not the kind of overt xenophobia used for the vast majority of speciesism posts. Would people who use the speciesism tag object to seeing something like this in there?
(I suppose a related question could be if a racial fetish tag is warranted, but I assume it would be too niche.)
