no Joseph
I have studied fake halacha and like you are quite versed in the subject.
As such presents, cookies, smiling, singing, eating anything other than latkes and sufganiot playing anything other than dreidel are all issurei deoraysa and copied from goyim.
any other food served at Chrismaku parties is obviously copying goyim as is singing anything aside for Hallel (there are some modern poskim who allow songs from hallel to be sung even not in the context of hallel, but as you may know I am very frum when it come to fake halacha)
