On the basis of your post then, the next time Grendel uses the word Mucas about Anne Lucas I can fully expect this very same post aimed at him. Just for the record I Grendel's wordplay far more disrepectful when it is aimed at a woman.
I believe that the use of "Mucas" was merely to illustrate the stupidity of the name calling, "Fishface, Wisher, Faggot, Joyless, Shitfields, Sisued" etc, etc.
Nothing wrong with it if using a bit of wit, but very basic stuff.
Myself i prefer to think of her supporters as Ann-Droids, which fits nicely with my Ray-bots description of the slavish lovers of Ranson.
Personally nothing against Ann Lucas, and very much applauded her stand against Marlon King(for which many accused her of just being a publicity seeking split-arse, who deserved a slap).
