Hi Jonathan,
Thanks for posting. I am not seeing the matter in the same manner as you do, so I will respond to your points:
This misuses the name of "Christ"
I am not sure that it does. Christ can be honored in the hearts of Christians any day of the year—including December 25th. If the Christian claims to be celebrating the birth of Jesus, and is doing so in spirit and in truth, this can hardly be regarded as a misuse of Christ's name, just because the date on the calendar says "December 25."
On the other hand, if non-believers celebrate something they call "Christ-mas," and if they recognize that the day is named after Jesus Christ, then they are taking the name of the Lord in vain—a bad thing to do, but probably not the worst of their sins. They would be doing the same thing if they attended a church and sang from the hymnal.
-has an unbiblical date and many details
Yes, it does. Though this does not, in itself, make it evil. One could celebrate the birth of Jesus, if one wished, any day of any month he/she chooses, since there are no biblical instructions about the celebration, nor the non-celebration, of Christ's birth.
Many harmless Christian practices are, in their detail, not supported by scripture. For example, the early Christians adopted the symbol of a fish to secretly identify themselves to each other, adopted Sundays as a weekly meeting day, and crossed themselves (like Catholics do) when they prayed. There was no biblical basis for their doing these things, but they seem harmless enough.
Most aspects of our present church services—the seating arrangement, the building itself, the program, the Power-Point presentations, etc.—do not correspond to any biblical details of church gatherings. We might think it would be better to do things in the biblical way, but it would not be possible to prove that these extra-biblical features are "evil"—nor necessarily displeasing to God.
has pagan history undeniably
This is increasingly well-known among evangelical Christians. However, when it come to cultural things, present realities often have little relevance to their origins. Many people in our churches have a personal history of having been servants of Satan, but this does not describe them today. They have been redeemed. One could well argue the same for many incidentals in Western Society. The days of our week, and the months of our year, are mostly named after Roman and Norse gods. However, these associations have long-since been abandoned as a result of the supplanting of paganism by Christianity. Nobody today venerates Thor on Thursday, though we still call it by that name.
Similarly, for over 1,600 years, no one (with the exception of a handful of modern pagans) has celebrated the winter solstice, or the pagan deities formerly associated with it, on December 25th. Certainly, not one person in a thousand associates the Christmas tree, the presents, the wreaths, etc. with their original pagan uses. Today (and for a very long time) they are, in all hearts and minds, either associated with Christ—or with nothing at all. They are no longer pagan practices.
Let me give an analogy from a different realm of behavior. Since the Bible says that a woman should not wear what pertains to a man, there are some Christians who believe that women should not wear pants. However, pants are no longer a distinctly male style. Perhaps the first person to introduce the wearing of pants by women in our society was in violation of this command, but the woman who wears pants today is no longer doing so. Not only are pants today an acceptable style for women, but there are styles of pants that no self-respecting male would wear. Customs change. The first innovators of the change may, at times, be rebels who violate the spirit and the letter of biblical instructions, but once the change has become established in the culture, there is no longer the same meaning to the actions. The meanings of some things change with the change of culture, which transforms their moral and spiritual significance.
Christian influence in Western Society, long-ago conquered paganism and redeemed many mundane practices which used to be done to honor evil deities. The kingdoms of this world [are destined to] become the kingdoms of our Lord and of His Christ" (Rev.11:15). Over 1,600 years ago, when someone wrongly syncretized Christianity with paganism—relabeling pagan customs as Christian ones—it was, no doubt, a bad decision. But that was long ago, and the taint of original pagan associations has dissipated over the centuries.
The introduction of pagan elements into Christianity cannot be recommended, but whoever did that has been dead for a millennium and a half, and when we bring a tree into our home, it is not a pagan action, but an act of Christian intention,for many—and, for others, a mere interior decorating decision. In the worst-case scenario, it is the bringing of an idol into the home. However, I don't think I have yet met a family that worships their tree, so this must be incredibly rare, if it happens at all. We could as justly condemn the introduction of potted house plants.
I suppose the most valid criticism of modern Christmas would not be of its corrupt religious origins, but its present secular commercialism. Even this, though, can only be a valid criticism if we are supposed to be keeping Christmas a sacred day—and you and I agree that there is no biblical obligation to do so. If we are not required to have a religious holiday on December 25th, who can object that it should become a secular occasion for unsurpassed gift-purchasing and giving?
(C.S. Lewis wrote a humorous satire on the commercialism of Christmas, which can be read here:

Not only has Christmas lost, to our culture, all of its former pagan associations, but it has also taken on specifically Christian ones—e.g., the ubiquitous manger scenes, and cards depicting scenes from the biblical birth narratives, the singing of overtly Christian "carols" in secular shopping malls, the lionizing and legendizing of a Christian saint known for his generosity, etc. All of these reflect distinctively
Christian influences upon the holiday. No self-respecting pagan would own the day in its present form.
poses an unnecessary risk to stumble a weak believer
I have a hard time seeing this possibility. There are very few people whose consciences oppose these customs. The few who do are usually pretty strongly opinionated about the matter, and are not likely to cave-in and get a tree, just because they see others do so. If there are people who think these things to be sin, then it is more likely that they would be influenced to go against their conscience by the generality of Western Civilization's Christmas practices than by their knowledge that you, personally, happen to have gotten a Christmas tree.
