I'm... I don't think it's racist if they aren't human? And I'm not sure, I didn't meet them personally. My friends went to them to revitalize their firebending, and apparently the dragons taught them an ancient bending form that also happened to look like a dance.

I didn't know dragons existed on other worlds too, though! Maybe there is a sasquatch back home and we don't know about it, especially if there's only one. That seems very lonely, though, to be the only one of anything.
