If the Jews want to make a big deal about a Jewish holiday, then they can emphasize Rosh Hashana, Yom Kippur
How do you "celebrate" Yom Kippur? By not eating or drinking and, to some extent as with Rosh Hashana, sitting and reflecting on the wrong you did to others in the past year and atoning for your sins. Thanks, Petermillman1.
Hanukkah is not a holiday
Chanukkah is indeed a holiday and it's been celebrated for longer than has Christmas, although, I grant you, it's a minor holiday. Nevertheless, you ought to worry about traditional European winter holidays "stepped on"/expropriated by the Christian Christmas.
you can’t find it in the Jewish version of the Old Testament.
You are confusing Judaism with Karaism. Karaism only cares about what's in the Hebrew Scriptures, but there is rather more to Judaism than what's in your translation of the "Old Testament." You have about 2,000 years' worth of catching up on the history of Judaism to do if you want to know the difference between what Jews believe and what you think they believe.
As a Greek Orthodox Christian , I find Hanukkah to be very offfensive.
So, as an Orthodox Christian, Chanukkah isn't the season, because Orthodox Christmas isn't until January 7, right? Oh, you're Greek Orthodox, and your church moved the date of Christmas forward two weeks to be more like the Western Church. So much for "stepping on" other people's holidays.
I imagine you also believe that Passover is "stepping on" Easter, even though the accounts of the Last Supper in the Gospels portray a Passover Seder. Just the kind of thing that Orthodox priests used to rile up their congregations before setting out on the traditional Easter pogrom.
