Welcome!
— Is the Quran the truth or is it just stolen ideas from other religions put together by a mad man or a man who was quite possibly visited by a demon rather than an angel?
Another alternative is that the writings are the work of his disciples and they got as close as they could to expressing what they understood his teachings to be. That is what happened to Buddha and to Jesus.
— Are the JW the only ones who acknowledge the name of god and use it in their religion?
Absolutely not. The Authorized Version of the Bible included the name in four places, if it wasn't acknowledged or used by other religions it would be anywhere besides in JW literature. But the name of God is YHWH, not Jehovah. The closest we can come to the divine name is the consonants.
— Why are the "elders" allowed to kick out or as i feel "judge" another witness?
Because the Governing Body said they can. Why can the Governing Body grant that authority? Because the Governing Body says it can.
— Is it really logic to think that a loving and caring god would condemn his creation to hell?
In my opinion? Not for an unending time. But for an unspecified time, sure. Not very different from the way those in Sodom and Gomorrah died, actually.
— What is the closest religion to the truth other than JW?
Christianity. The same would be my answer if you had asked about LDS, Catholicism, Lutheranism, Baptist or any other organized religion that claims to be Christian. Christ didn't have a structured organization. C.T. Russell actively preached against developing any organization and in favor of an open and interacting association of Christians.
But, these are only my answers. What are your answers?
