On the other hand, here is a web site that claims that the Hykso were none other than the ancient Jews! (makes a pretty good argument for it, too....)

:') But that isn't true, and the arguments aren't sound, just rehashed anti-Jewish junk, some of which dates to ancient times (Apion, most notoriously; but also Josephus, who wrote "Against Apion" as a rebuttal to Apion's "Against the Jews").
