Can you understand how it was misinterpreted, though?
You come to a place where there are people of many faiths, and announce that your nonreligious work had a religious prayer that honored your religion alone, and that you are happy about it.
I'm Buddhist, and thought it came off as an "We Win!" kind of announcement.
As a Buddhist, I imagined myself in a room of people all praying to Jesus, and not being Christian myself, how awkward that would feel.
I don't think it was meant like that. I've read the thread from the start, and I think you were just happy that you were able to express your faith at work, as we all should. However, when it seems that one faith is endorsed, and others ignored, or someone takes on the assumption that "we're all __________ in the room, right?", it begins to detract from what it is trying to do. It begins to divide and exclude those who aren't praying to your God. It puts people into the role of being the "other" - Muslim, Jew, Hindi, Wicca, or Atheist. They feel isolated, disconnected, singled out, left out.
And not really what Christmas is about.
You know what I see this time of year, as a teacher of English? I have Muslims that wish me Happy Eide, a celebration of Abraham and God giving a ram in place of Isaac. I am wished Happy Chanukah by Israelis, who celebrate the burning of an oil lamp that normally burns for one day, but burned for more than a week. I am wished Merry Christmas by people who celebrate the gift of Jesus to teach us how to love.
I am wished Peace on Earth and Good Will by all of these people from all over the world, in their own way, in their own religion, and when I really think about it, it's unexplicably beautiful.
