In the sake of fairness...it doesn't look to me like they use any religion-specific logos at all. I saw "Holiday Season" with the usual snowflakes and snowmen...but no Christmas trees, Chanukah decorations, or Kwanzaa references either. They don't appear to do anything for Yom Kippur or Roshashana...no GOOGLE decorations for Ramadan either...closest thing they seem to get is celebrating Chinese New Year.
So at least they are consistently ignoring almost ALL mainstream holidays with religious meanings...I suppose Halloween could be questioned, but most would agree that the pagan roots of the holiday have been completely overtaken by the commercial reality it has become.
