Excellent post - funny, witty and true.
The OP wished to convey a pleasant and warm Season's Greetings to all who post here or are members here, and I have no quarrel whatsoever with that.
Odev's post cleverly draws attention to the fact that the time - of days - of the shortest day/longest night of the year (which feels like an eternity i northern Europe) has been acknowledged by festivals marking this by a significant number of different cultures, one of which was the Christian Church which followed the Roman Empire.
There is a nice, big, historical (and theological) debate over the fact that the Christian World which succeeded - supplanted indeed - the Roman world superimposed its own celebrations on dates or times which already celebrated something such as the turning point of the year which would give rise to the rebirth of longer days, and eventually, spring.....
Indeed, one can argue why this happened (and dark suspicions beg certain questions, which is an entirely separate topic), but, while I don't deny the theological dimension, (and equally, I don't really subscribe to it, personally), I will happily take - and return - Seasonal Greetings in the spirit of benevolence and bonhomie in which they were given.
Cheers and a Merry Christmas to you all
