I don't think it's a disorder to hate something; we're likely to have strong likes, dislikes, and love/hate certain things and may not know/remember why -- there's nothing "wrong" with that, I don't think. And there's no law that says we have to analyze it either if we don't care to know why we have a strong feeling about something, even if it's only a name. We're born/have built-in strong likes and dislikes! So? Every seen "Funniest Home Video" when they feed the baby something "nasty" like liver and the face she makes? :-)
