My Wikipedia search tells me that Yom Kippur is a day of feasting, singing, and celebration of the mitzvah and everything.
From the Christian's warp-drive perspective, I'd like to offer some technical advice to your developing culture.
Some things to keep in mind:
--It's not okay to fly planes into buildings, even if it is to glorify your pagan egregore god.
--It's not okay to fry your own subhuman pigs for the sin of rejecting the authority of the Talmud.
--The hair of a white dog does not actually have magical powers.
--If two women are sitting on opposite sides of a road facing each other, that does not mean that they are witches.
--It's okay to eat pork. Eat all you want; it's delicious and good for you. It won't make the sun go away.
--It is not okay to nullify oaths in your heart.
--The property of a Gentile is not the property of a Jew.
--It is not okay to stab the am ha'aretz, even on the Day of Atonement.
--One clan is not better than another. You are in no way 'chosen.' This belief is a disgusting supremacist illness, as misguided as chanting over toenail clippings and bowing down to a pile of rocks.
--Lying with a nine-year-old boy or three-year-old girl is just sick.
--It's not okay to lie to, steal from, and trick members of other gaming groups. Treat your neighbor as you would be treated.
--Dog shit does not make good spaceship fuel.
--It's not okay to regard all the Jews in Poland as worth less than one pig in Palestine.
--Contrary to what some Rabbis think, there was nothing good about Adolph Hitler. He was an evil man. Stop celebrating him as the Jews' Avenging Angel.
--Amalek is not hiding inside the Netflix mailer. Don't worry; he's not going to spring right out and ruin Hannukah for everyone.
--It's not okay to punish our Lord and Savior, Chris King, for pointing out that maybe we've got some theological, uh, errors that caused us to teleport ourselves to the Year 500. It's not Chris' fault. This is a bit like Lynndie England --that darling little pixie-- blaming the news media for all the hubbub surrounding the Abu Ghraib scandal.
--Yours is the Affirmative Action Baby of religions. The rest of us are getting impatient with your theological bumbling. We've cut you a lot of slack over the years because everyone hates you so much and just wants to make handbags out of you. But tighten it up over there already. And stop ruining everything with your withering death touch.
Aside from those few advisories from someone with an advanced perspective, I'd say you're well on your way to joining the Federation of Human Cultures. You'll be setting aside your bones and piles of rocks in no time!
Turn from your pagan bone waving! Take your rightful place among the great Abrahamic religions! Soon, you too can be as esteemed as your Christian and Muslim brothers! Come on, join the party! Stop playing with your toes and finger-painting with dog shit!
So happy Yom Kippur, everyone! And go easy during the pie-eating contest!
