Charlaquin
Goblin Queen (She/Her/Hers)
Many of the people quoted have been quite clear on the matter. In particular, I think @Gradine was quite explicit and clear about their criteria.None of those posts articulates a clear reason why the fey/humanoid distinction is the crux to them. They are flat statements of personal opinion without explanation.
In contrast, those who object on the grounds of links to RW bigotry have been crystal clear.
