Based on a saint though ....

She needs to apologise if you ask me. Father Xmas wasn't a real person but an idea, a kindly old man who bestowed gifts on people. The colour of his skin shouldn't make a bit of difference.

Well when you look at the areas they came from I would suggest she is wrong on one of them at least. Apologise ? well she is as entitled to her beliefs as anyone else but possibly she could be told to refrain from spouting them in quite this way again.

Based on a saint though ....

In England the earliest known personification of Christmas does not describe him as old, or refer to him as 'father'. A carol attributed to Richard Smart, Rector of Plymtree from 1435 to 1477, takes the form of a sung dialogue between a choir and a figure representing Christmas, variously addressed as “Nowell”, “Sir Christemas” and “my lord Christemas”. He does not distribute presents to children but is associated with adult celebrations. Giving news of Christ’s birth, Christmas encourages everyone to eat and drink: "Buvez bien par toute la campagnie,/Make good cheer and be right merry."[1] However, the specific depiction of Christmas as a merry old man emerged in the early 17th century.[2] The rise of puritanism had led to increasing condemnation of the traditions handed down from pre-Reformation times, especially communal feasting and drinking. As debate intensified, those writing in support of the traditional celebrations often personified Christmas as a venerable, kindly old gentleman, given to good cheer but not excess. They referred to this personification as "Christmas", "Old Christmas" or "Father Christmas".[3]
