Hi tamiloo
as a Christian I am blessed to wish you Merry Christmas
however......
"Happy Holidays" is not just a "politically correct" greeting but one that respectfully acknowledges the other faiths and cultures who celebrate at this time of year, but for reasons different that we as Christians do.
Those of Jewish faith begin the observance of Hannukah tomorrow, while those with African roots celebrate Kwanza at this time of year and many also celebrate Yule etc
We have members of all faiths and cultures here, and so we wish ALL "Happy Holidays"
