AS FAR AS THE "RIGHT RELIGION" QUESTION -
Go waaay back in history, before there were Jews or anybody worshipping an omnipotent vicious desert Sand Fairy.
Religions did so many different things, depending on where people lived. In ancient Greece there was a whole panopoly of gods to choose from - Zeus, Minerva, etc. In India, hundreds of thousands of gods to worship, as you saw fit. In Africa there was and still is animism - spirits in trees rocks streams and the wind. Egypt had Anubis, Osiris, Nut, Rah and many others.
If none of these religions was the right one at that time, who is to say that in our time there is any more likely to be a right one.
Have no fear - time passes, and the world unfolds, along with your life the way it should. Whatever choices you make your life will happen anyway. Use it with self-respect and compassion for all living things. For some things there is no real answer. The monotheistic religions claim to have it, but none of them can agree with each other.
The JWs are only "united" in so much as they are forced into conformity, by means of fear, the DF stick where they cut you off from loved ones, and death threats of Armageddon. Take these away and there would be a lot of open dissent and schisms. In E. Europe there are Jehovahs Witnesses who say that Brooklyn Bethel and the GB are all apostates, and they refuse to follow them.
