Daniel:
I understand you're frustration. This site can be confusing. Those here are ex-Jehovah's Witnesses, and many have left feeling numb and angry at the mind control the Society has had over their lives. I was a JW for 21 years, and my faith in Jesus has allowed me to get over the bitterness and anger, but it takes so much time for many others. JWs are considered a cult for the following reasons:
Theologically - From a Christian perspective, a group may be defined as a cult when it radically deviates from the essential historic and biblical beliefs of the Christian Church. For example, this would be seen in the various groups which deny the Deity of the Lord Jesus Christ. JWs believe Jesus is only an angel (which you will find out if you study). There are other deviations that they teach which go against the true gospel.
Sociologically - A group which uses mind control tactics such as subtle fear, guilt, and pressure etc. can be classed as a cult. Daniel, from the outside you might think the JWs are like any other group. But field service is a pressured assignment, the fear of never talking to your family/friends again if you decide to leave is a fear of many. And the guilt of missing meeting, field service, not studying their publications is heavy. Also, if you become a JW, you are told to give up all friends and limit association with family members who are not JWs. They don't tell you this right away--it's told to you mid-study when they feel you are "conforming" as a good JW study and attending meetings regularly.
Cults add their own efforts, their own works of righteousness to the finished work of salvation accomplished by Jesus on the cross. All Cults say that Jesus' sacrifice is sufficient, but our works must be 'mixed with' or 'added to' His in order to prove that we are saved and worthy of salvation. JWs say one thing but believe another. They maintain that they must prove themselves worthy and that they must try their best to please God and prove to Him that they are sincere, have worked hard, and are then worthy to be with Him. But Daniel, this is absolutely wrong. The Bible says that we are saved by grace not by works "For by grace you have been saved through faith...not as a result of works, that no one
should boast, (Eph. 2:8-9, NASB); not by anything we do "For we maintain that a man is justified by faith apart from works of the Law" (Rom. 3:28, NASB). Because if there was anything that we could do to merit the forgiveness of our sins, then Jesus died needlessly "nevertheless knowing that a man is not justified by the works of the Law but through
faith in Christ Jesus, even we have believed in Christ Jesus, that we may be justified by faith in Christ, and not by the works of the Law; since by the works of the Law shall no flesh be justified...I do not nullify the grace of God; for if righteousness comes through the Law, then Christ died needlessly (Gal. 2:16,21, NASB). So JW meeting attendance, field service does nothing. And the doctrines of JW are all opposite of the true gospel (please note that their New World Translation of the HOly Scriptures is NOT an approved translation).
The Cults will often cite James 2:26 where it says that faith without works is dead. This, of course, is correct; faith without works is dead. If you have real faith it will result in real works of Christianity. That is what James is talking about. But he isn't saying that our works are what saves us, or that they, in combination with the finished work of Christ, save us. James was telling us that if we say we have faith (James 2:14) but we have no works, then that faith won't save us; and faith is what saves us, "Therefore having been justified by faith, we have peace with God through our Lord Jesus Christ"
(Rom. 5:1). It is faith that saves. Incidentally, it should be noted that it is not faith only but faith in the proper object. Just having faith in something doesn't mean you're saved. Faith is only as good as the object in which it is placed. That is why it is important to have the True Jesus. Because if you have great faith but it is in the wrong Jesus, then
your faith is useless.
I hope some of this helps. Please e-mail me if you have more questions.
