bill, you doofus!
it's spelled idiolect

tsuwm! I am shocked, simply shocked that you, of all people, would make such a terribly unfounded accusation about our dear Dr. Bill! No less prestigious an institute than Old Dominion University spells it ideolect. See http://courses.lib.odu.edu/engl/jbing/444-ideolect.html. We know that this institute is prestigious because, on their home page (http://www.odu.edu/) they have a picture of a person of color standing in front of a white board with the words Creole Culture legible behind him and two dead white guys wearing robes with fuzzy black bars on them shaking each others hands.
