I strongly suggest you do some real reading about the history of the Bible. Not least the way the Watchtower has shoehorned in the name Jehovah where it wants, removed any trace of idea of Jesus being God (before Abraham was, I am versus I have been). There's a whole part of Revelation (I'll find the precise quote shortly) that the Watchtower conveniently ignore that proves their changes of Lord to Jehovah not Jesus as incorrect. The Watchtower also conveniently ignores the Catholic and Eastern Orthodox Bibles too which have many more books than the Protestant (eg 1 and 2 Maccabees in the Catholic Bible, 1, 2, 3 and 4 Maccabees in the Eastern Orthodox).
I also strongly suggest you study more of their beliefs that Christ isn't our mediator, the lowly class who'll only inherit earth, Jesus is only mediator to the 144k.
I absolutely deny your assertion that disfellowshipping is an extreme event. It happens far too often for people living what most would consider normal lives. And don't forget the fact that those who are even your own family are not spoken to until they're back in good standing.
Don't even get me started on the memorial. Christ was very clear in His directions that if you wanted to have part of his sacrifice you had to partake of the bread and wine, and again every year the Watchtower has people around the world thumb their nose at the very same symbols.
What about the pyramidology and other occult practices from which Rutherford in particular grew the faith? Or the back pedalling after 1975 to Jesus have returned invisibly in 1914?
Don't go into this blind, educate yourself on both sides of the argument because all the WT will do is offer one sided information in the most didactic way with threats of being df'd if you begin to question and read other sources.
Finally if you aren't baptized and aren't publishing you categorically aren't included as Jehovah's Witness. That's the point. You make a public declaration and promise to Jehovah by being baptised and by publishing, that's how you become Jehovah's Witness, otherwise you're just another non-member.
