Black Is Ugly

I heard the following conversation on a TV show in which the host of the show discusses with college students regarding all things about their institution.

Host: Oh! Why do you call that dog ‘ugly’?

Student: You see, the dog is black in colour, so we call it ugly...

I might not have reproduced the conversation verbatim but the gist is intact. I don’t know if anyone found the response insensitive, but I felt it was nauseating to say the least.
