Is Sasuke a racist? I think so, yes. He's a case study on racism. Always going after black shinobis like killerbee & Raikage, also he's arrogant, ignorant, always feeling he's superior to others cause of being an Uchiha. He'll prolly target Omoi & karui next. Oh and we all know the extent of his hatred, he hates every1 and wants to kill them all. Seems like Genocidal tendencies run in the family and the uchiha clan.
