Well ... you would be surprised by the number of muslim who celebrate christmas here.
Don't forget that Jesus/Aïssa is a prophet too
I asked my colleague for him it's named : "Aïd al mouloud" and he don't see any reason to not please the kids ... but he is Algerian not a middle east scumbag ...
I'm not sure but I think there is jewish celebration too in December ,and I know some jewish who celebrate christmas too for the kids
Btw there is actually a discussion about adding 2 new public holiday : Yom Kippour and Aïd el kebir/Tabaski.
