I never did compare Hannuka with Kwaanza, I simply used both as an example that neither one of these events is anywhere near as important to their followers as Christmas is to Christians.
Christmas became a national holiday because of its supreme importance to Christians in America, whereas neither Hannukah nor Kwaanza would be given that kind of prominence even in their lands of origin of Israel and Africa. They are comparatively minor events. Hence, neither of them belongs in the same category as Christmas, and they (by design) serve only to bring Christmas down to some theologically insignificant "holly jolly holiday season".
