I wouldn't get my hopes up that soon birthdays will be OK. They seem to be cracking down on valueless things, including any fun. And, it will probably be lumped along with valueless things. Which sucks.
Now, my view on birthdays. First, if you are going to follow the Bible, you will notice that Job's sons celebrated their "special days", which would mean birthdays with logic that is no more specious than the Filthful and Disgraceful Slavebugger has come up with to ban birthdays. And, Luke 2:10-14 blatantly tells of perfect angels celebrating Jesus' birthday. That blatantly contradicts the Tower view of Christmas being unscriptural. Based solely on this, birthdays are not unscriptural.
Additionally, does celebrating a birthday violate the Prime Law (that is, the law that would, if followed, allow society to flourish)? Anyone that can show how volitionally celebrating one's birthday amounts to initiatory force, threat of force, coercion, or fraud (without lying to do so) could post a logical reply to the effect. As far as I know, it doesn't. Celebrating birthdays, therefore, is not morally wrong.
What are the fruitages of celebrating birthdays? No, I am not advocating going out and getting plastered drunk or stoned and then driving (that is, unlike celebrating birthdays, genuinely harmful). I see absolutely no harm in children opening up the presents and eating cake and ice cream. To the contrary, children look forward to opening up their presents. They remember what it is like to anticipate it, and then have fun that day. The balloons and party items add to the good times. Generally, the worst after-effect of these parties is the mess left to clean up. But, it is worth having the children having fun for spending an hour or two cleaning up a mess.
No, I am not for forced birthday celebrations. Many people choose not to celebrate their birthdays, and that is OK. Some are depressed around that time. And, it is common for singles with birthdays nearing 30 and higher to not want to be reminded that they are getting old. Many people will dread their 30th, 40th, 50th, and 60th birthdays for that reason alone. But, those who do enjoy celebrations (and especially children) should be allowed the free option to celebrate their, or their friends', birthdays.
