re: Ahem.
First: I'm a convert to Judaism, and one with Celtic roots. I find nothing inherently wrong -- let alone anti-Jewish -- with pine boughs, mistletoe, the red/green color scheme generally, and other trappings of the Winter Solstice observance my ancestors held before the Xtians subsumed them.
Second: I've been known to "Xmas shop" in the past, if there were someone I wished to give a gift to... and wrap it in the appropriate shiny paper and ribbons.
This year, lacking the second, there's no incentive for the first.
