Hornsby [Hayley Thompson]

I agree with Hornsby that derogatory words are "useless" since they are only used when the speaker wants to say something negative about another person, but does not have anything substantial to claim. If a speaker has a legitimate reason to dislike another person they can describe this without using a derogatory term. It is only when the speaker feels that their argument against the other person is feeble or unfounded, that they may find themselves throwing out derogatory terms, to make that person look bad. Most people have no use for these terms because they do not describe other people as objectionable without a reason, or almost never have an audience that approves of them doing so.

While I do not blatantly disagree with any of Hornsby's arguments, I have some trouble understanding the example of Hare's made-up word "doog", what it is meant to illustrate, and why Hornsby argues against it.  

Derogatory words seem to have the same referents and denotations as others that are not derogatory, but instead have different, negative, senses and connotations. When we object to derogatory words, we object to their senses rather than their referents.
