How many JW's like to debate / discuss the doctrines and/or practices of the WBTS? Or is it safe to say "Sadly, most JW's do not want to hear such things"
Funny, but as it is a tradition in the JW community to be very date focused (1874, 1879, 1914, 1918/1919, 1925, 1975 etc), many JW's believe that for the outside world the date of 25 December is essential. Well, as the date was set by people who are not alive anymore, most people today either believe the date is correct and those that do not, do not really mind. In all cases, the date was not set by any of the people who live today. Therefore, the date has become more a so-called given and people just act accordingly. Compare that behaviour to JW's who act according to the dates the gb has set for the so-called invisible enthronement of Jesus in 1914. A date that is not found in the bible. As most JW's will likely say that they do not mind the accuracy of that date but more the meaning they attach to that event, so do most people who celebrate Christmas
Are the customs linked to Christmas found in the bible? No,not in the sense that it has evolved to. But then again, is that relevant? Are these people dishonoring God because they give presents? They give food to the poor? They spend time with family and friends? They think about Christ?
What is more a way to dishonor God? Impose doctrines on people in the name of talking on behalf of God and at the same time revising these doctrines many times, like the use of blood, organ transplant etc? Or is it to shun even you children because they are, according to 3 men, not repentent (enough), for which you cannot find any scripture in the bible to support that shunning practice?
My point, do not look upon people who celebrate Christmas because they like to use that even to put more effort into helping others. Yes, in many western countries it has become a commercial event. But that is the commercial world, not all who participate in Christmas would support that.
