You need to know the history. At Abuzz, Miller was Dr. KaK,and was universally despised. That's because she is racist, and a Jewish bigot who considers everyone else to be inferior to Jews. When she came here, she wanted to cultivate an image of gravitas
, an image of intelligence and reasoned debate. (An ugly joke if you follow her posting history carefully.) But she really hates Democrats and blacks. When Deval Patrick was elected to succeed Romney as governor of Massachusetts, she just about had a cow. The Foofie sock puppet was created in mid-2007, after Patrick had been elected, and Miller has been using Foofie ever since then to express her more outrageous and bigoted opinions. Foofie is an outrageous stereotype of a bigoted Jew, and gets to say all the things that Miller (formerly Dr. KaK) wants to say, but can't if she intends to maintain her phony image. They don't actually disagree, it's just that Foofie gets to say more outrageous things. Miller disdains blacks and the Irish. Foofie says hateful things about them.
In a thread in which Miller was engaged, Miller made a statement about Social Security, and, when questioeds, Fooffie responded. Challenged on why she had answered, Foofie said that she knows how Miller thinks. Then Foofie denied knowing who Miller is--even though Foofie had just said that she knows how Miller thinks. Suddenly, Foofie knew that Miller lives in Boston (or the Boston area), and works in the health care field. Then Foofie suddenly knew the specific Jewish, ethnic origin from which Miller derives, while claiming to derive herself from a different Jewish ethnic group. It was not at all a convincing performance, and Foofie continually contradicted herself. Look closely--they don't disagree, it's just a difference of degree in how they express themselves. Foofie is Miller's sock puppet.
