The Simpsons: a family of Sephardic Jews?

The Simpsons Archive has a strange thesis that holds that the Simpsons are actually a family of Sephardic Jews:

The Sephardic Tradition encompasses the culture of the Jews who descended from Spain prior to the expulsion in 1492. However, a broader interpretation also includes Jews who originated from Turkey, Greece, Italy, England, the Ottoman Empire and other lands. The tradition today has come to include not only those with geographic ties, but also those with links to the fascinating culture. Many Jews know that Sephardim eat rice and beans on Pesach, and know of the unique torah trope of the tradition, but little else. However, many Jews, and even non-Jews are exposed to aspects of the Sephardic tradition and culture without even knowing it. [...]

According to David Gitlitz, in spite of the attempts of crypto Jews, most of these conversions had been completely assimilated by the end of the 17th century. Gitlitz say that the meager remnants that resurfaced in the 20th century are the exception to the rule. There is evidence to suggest that the writers portray the Simpson family as crypto Jews of the assimilated nature, so much so that they no longer know their true identity. Mark Pinsky, author of The Gospel According To The Simpsons, argues that "The Simpsons from time to time suggest an underlying element of what might be called crypto-Judaism" (121). For example, a menorah is found in the Simpsons' storage closet, with no explanation."
