Christmas is commercialised, I personally detest that commercialism as well. However, I do see the problems behind any good intent at that. That occured during the darkest periods of christianity, where religion and politics got involved with each other. Some pope of that time declared to observe the birth of christ over certain roman sun god's birthday instead. The intent was for a good cause, but all human intents were flawed. As we all know, Romans being Romans, they're all sinful indulgers, so all pagan practices got dragged in as well.

Long after it got better, it being a very family based observation and celebration, that was christianity at its best.

However in the modern day context, some christians say that it is only right to show off all that God had richly blessed them and made them stewards to Him by flaunting their wealth to all around. Such is a rather twisted perspective. In more practical terms, whatever wealth should be used to aid instead of having it spent on plain "advertising" their richness.

The true birth of Christ, doesn't fall on 25 Dec or 6 Jan.

Truth is, it isn't easy being christian, when all occurs in life starts getting into the picture.
