I'm not a Christian either, but I'm not offended by the image. Perhaps it should be said that the wreath is considered a Christmas decoration, and there isn't another religious symbol or decoration shown. Red and green (colors of the words Sideshow and Freaks respectively) are also considered Christmas colors. But Collector Freak, if it helps, the snow is blue and white, the colors often associated with Judaism, and here in the U.S. apparently with Hanukkah. OK, I admit that association is a bit insulting and for that I apologize. It also makes me wonder what a person would have to drink to do that. Again, my sincere apologies. My feeble attempts at observational humor and lightening the situation. I personally wouldn't mind seeing a menorah, Star of David, or Kwanzaa symbols or decorations, among whatever other religious symbols there are along with the image, provided they are nice or even beautiful to look at. In fact, I'd prefer it in a sense. I'm agnostic, but that allows me to inherit all that I find beautiful without prejudice and of my own accord. The problem with trying to display a number of different religious symbols and decorations arises when those you've forgotten feel left out, as is true here, or those who don't celebrate certain or any holidays this time of year or at all feel like they are having religion thrown at them.
Collector Freak, I noticed, as I was typing this, you added your response regarding the wreath (I kept a second window open for various reasons). It seems it was added without knowledge that wreaths are considered typically a Christian decoration. I hope no offense is taken. I fear a compromise might be difficult to work out, however, even though some religions may have already adopted others' traditions, symbols, or decorations, because not every faith can be covered. It also seems that none can't be covered easily either.
