I don't celebrate Xmas because it is a shitty commercial holiday where people are pressured to show their "love" for family and friends by buying things.
It is called the "jolliest time of the year," yet statistically it is one of the peak times for suicides.
People trample each other to death during sales to get whatever item is hot that season.
It is pretty much the worst of materialism and capitalism all condensed into one shitty holiday.
