The Santa Lucia hat was my idea and I apologize if it caused any offense. We like to recognize holidays of various traditions that occur around the solstice and the changing of the year on the Gregorian calendar. I have fond memories of Santa Lucia celebrations at the Swedish-American church I grew up in, so I wanted to start Winter Bash with the crown of candles that symbolize light overcoming darkness.
Even though the hat was named after an Sicilian martyr, it wasn't intended to be especially Christian. Outside of regions of Italian and Scandinavian culture, I doubt most people even know who she was. To me, Santa Lucia celebrations are more in line with getting your annual dose of lutefisk than anything religious. But I can certainly see how that would not be the case for someone who didn't grow up the way I did.
We also do a Hanukkah "hat" every year. We've done a menorah and a dreidel in the past. This year, I wanted to dig a little deeper, so I suggested the symbol this year would be gelt. Thanks to timezones and our forgiving hat distribution, you can earn that hat right now.
