Thank you very much. Hopefully everyone will learn from what each other does right. Admitting one's own weaknesses and the strengths of others is the only way to really improve one's self.
Your questions are fair, but I'll respond in reverse order to keep the shorter answers on top... more readable that way.
3- Both of these dates are well known and admittedly not handled properly... however, calling them "False prophecies" isn't exactly fair. The 1914 thing was a prophecy in the book of daniel. Obviously, JWs of that time hoped it meant more than it did and we were wrong about the interpretation. But it wasn't a prophecy that "JWs made" only one we misunderstood. To be fair, it is a date the bible seems to point to, and it was a very significant year on earth (The beginning of the largest war in history, with resulting wars still being waged today). We were arrogant in our insistence of the interpretation we hoped for, however it was a bible prophecy, not ours. 1975 was clearly not a prophecy either. It was specifically an observance of the end of 6,000 years of human history. One made by many churches, and specifically declared a "holy day" by the catholic pope of that time. There was a similar "oh no, this is a round number, the world may end!" scare just as most of the world feared at Y2K... but that's the human fear of round numbers... not a prophecy. You can download the 2010 Watchtower Library online and go through all the watchtower articles published. Run a search for yourself of the word "1975" ... there are quite a few references that 1975 may be "very significant" ... but there is never a claim that "God told us that 1975 will be the end of the world!"
For example:
1975 will, no doubt, go down in history as a year of very significant and interesting events, among them being the four-day Divine Sovereignty District Assembly of Jehovahs Witnesses. Especially will this assembly be long remembered by those able to attend.
Quotes like this one (talking about how they have a nice convention planned this year) are usually taken out of context to insinuate that the "very significant event" is the end of the world.
2- The watchtower isn't supposed to be "God's word on earth" ... It's one publication from the "Watchtower, Bible and Tract Society" (WBTS), and like all other publications are intended to be a study guide or pre-written, interactive sermon. Messages are given as with any sermon and should be considered as with any sermon, however, is written by fallible men like any sermon. They spend a lot of time researching, site scriptural references constantly and generally word things very carefully... however not all articles are as good as others, just like not all sermons are as good as others.
I believe the point of this question was why we assume we're "the true religion" and all others are not. Simply because we assume our interpretation to be correct. We consider ourselves to be true because we teach the truth. It's not that "we" are special, but because the bible is special and we assume our interpretation of it is the most accurate. If someone else were as accurate, they would be equally true. (Of course, anyone who believes something believes that what they believe is true).
Good starting point is Jeremiah 16:21:
Jeremiah 16:21 said:
Therefore here I am causing them to know; at this one time I shall cause them to know my hand and my mightiness, and they will have to know that my name is Jehovah.
We consider it quite disrespectful for people to change that last word when God himself states that by his hand and mightiness, we will know that last word. Transliterating it as "YHWH" or "Yahweh" or otherwise attempting to pronounce the tetragrammeton, or even saying "HaShem" to acknowledge "the name" would be fine... but substituting it with an unrelated title goes too far, in our opinion
Point 1 warrants it's own post.
