Just read these quotes from the Haaretz article. I think they are clear enough, specially the "horrific night", "Christianity as waste material excreted from the body of the Jewish people" and "those who bow down before vapor and emptiness."
"For this reason, Nitel Night, from nightfall to midnight, is one of the few occasions when Hasidim refrain from Torah study. On this horrific night, they neither conduct weddings nor do they go to the mikveh (ritual bath)."
"The Knesset correspondent of the ultra-Orthodox newspaper Hamodia, Zvi Rosen, relates that celebrated Hasidic admorim (sect leaders) would cut a year's supply of toilet paper for Sabbath use (to avoid tearing toilet paper on Sabbath) on this night. Actually, this disrespectful act has profound kabbalistic significance, because kabbalistic literature extensively discusses Christianity as waste material excreted from the body of the Jewish people. Today, precut toilet paper for Sabbath use is available on the market; thus, the custom's relevance has diminished."
"However, the biggest paradox concerns the procreation mitzvah (commandment). It is recommended that the commandment be observed on Friday night, which is a holy time. Yet on Nitel Night, which has no holiness, it is customary to refrain from observing the commandment, because of the fear that a Jewish child conceived on Jesus' birthday could become an apostate."
"One Nitel custom in the Diaspora was to recite the entire "Aleinu Leshabe'ah" prayer out loud. The prayer includes the phrase "those who bow down before vapor and emptiness," customarily uttered in a whisper throughout the year, so that gentiles would not hear the words. On Nitel Night, it was customary, after it had been ascertained that no non-Jews were around, to loudly utter the forbidden phrase."
The only thing worst than the GOP is the Democratic Party, think about it!
