The question : What do JTF Christians thinks about the Secularization of The Christian New Year?
I think the answer is very simple:
Christianity never eradicated the Yule traditions of the German tribes of the pre-Christian period.
In ancient Rome they had orgies during the Saturnalian festivities.
Contemporary Yule Traditions
http://en.wikipedia.org/wiki/Yule
Many of the symbols and motifs associated with the modern holiday of Christmas are derived from traditional pagan northern European Yule celebrations. The burning of the Yule log, the decorating of Christmas trees, the eating of ham, the hanging of boughs, holly, mistletoe, etc. are all historically practices associated with Yule. When the Christianization of the Germanic peoples began, missionaries found it convenient to provide a Christian reinterpretation of popular pagan holidays such as Yule and allow the celebrations themselves to go on largely unchanged, versus trying to confront and suppress them. The Scandinavian tradition of slaughtering a pig at Christmas (see Christmas ham) is probably salient evidence of this. The tradition is thought to be derived from the sacrifice of boars to the G-d Freyr at the Yule celebrations. Halloween and aspects of Easter celebrations are likewise assimilated from northern European pagan festivals.
English historian Bede's Historia ecclesiastica gentis Anglorum contains a letter from Pope Gregory I to Saint Mellitus, who was then on his way to England to conduct missionary work among the pagan Anglo-Saxons. Pope Gregory suggested that converting heathens would go easier if they were allowed to retain the outward forms of their traditional pagan practices and traditions, while recasting those traditions spiritually towards the Christian G-d instead of to their pagan "devils": "to the end that, whilst some gratifications are outwardly permitted them, they may the more easily consent to the inward consolations of the grace of G-d".

New Year was a pagan Feast.
It became christianised during a couple of centuries.
The Church was not able to fulfil the policy of making 1 January a Solemn New Year.
The Catholic Church has a liturgical New Year, that doesn't coincide with the Feast of the Circumcision.
Today 1st of January is not being perceived by Christians as a religious day. (my opinion)
that doesn't mean it is "just another day"
It is a tradition that is older than Christianity, and we will keep it, along with the Christmas-three.
Christmas in Denmark, is still called Yule.
