Killer, I'm sorry that you have misread my unblock request. If you re-read it you will see that my use of "pop-eyed chihuahua" there refers specifically, accurately and unequivocally to the dog displayed on your user page and not to you. I cited it to explain to why I used that imagery in the WP:PA, as otherwise it would appear inexplicably random. The explanation was not, as you seem to think, offered in mitigation. Indeed my original unblock request, which I condensed at the request of admin Hersfold, stated: 

The following will help the reviewing admin(s) to understand what otherwise would appear to be a random choice of metaphors.[...] Killer has a picture of a pop-eyed chihuahua dog on her user page,  captioned “I look like this”; and she is in the habit of referring to herself, in her sysopping summaries, as a dog   e.g. “Puppy has spoken.” Stupidly I exploited this canine imagery at Killer’s expense.'' 

I edited out that section along with others in an effort to comply with Hersfold's request.

My unblock request in no way implies that it is 'somehow OK to insult' you because you refer to yourself as 'puppy'. It simply explains where the idea for the canine imagery came from. It does not attempt to excuse my using it to insult you.

I have apologised, and still do, for my rude and offensive references to you personally in the WP:PA; and ask that you graciously accept my apology as sincere, which it is.
