They are a ranked structured society as it seemed tho as the dragon knight was directing her as her superior by rank, not as a male to female. I dont think in her culture their is a distinction of male roles to female roles. They are all breed warriors (to what I figured) and its all about rank and prestige to their goddess. Different than in Drow culture where its about rank, prestige, and what sex you are born as. Toxic or tame masculinity or femininity by cultural standards for the gith I don't think exist by how they live. So if not racism than over zealous nationalism. Much like Helots to the Spartans, they were 2nd rate citizens. I figure the gith see all other races as 2nd rate races.

But back to the point, apart from laezel. I think most of the other races have a pretty standard "humanistic" standard of masculinity and femininity that Larian can bring to life(besides the drow and their matriarchies).
