<p>'half-breed', cross-breed, those words...don't you usually see him get worked up when his brother calls him 'a worthless halfbreed in the show? Or when Koga makes puns of Inuyasha of smell worse than k-9's(remember, Inuyasha's a half dog demon. Basically he Inuyasha gets pissed whenever someone throws negative adjectives alongside either crossbreed or halfbreed. Also, during his early life, he was shunned upon by most humans and demons because he was neither full human or full demon. From what I've seen of Republic City's citizens reaction to spirits as of Book 3, they don't have high opionions for spirits, and chances are it might be worse if there were any such crossbreeds. Conversely, while Korra is the only known hu man to recieve negative, or if at all any feedback from spirits, who's to say certain spirits would think equally low an opinion for crossbreeds?
