You won't learn much about Christianity from JW's. I have spent a lot of time with real Christians, so I know the difference. If you want to know how the JW organization operates, read 1984 by George Orwell. Then read The Orwellian World of Jehovah's Witnesses by Gary and Heather Botting.
I recommend college courses on church history, or even the textbooks for such classes from your nearest college bookstore if you want to learn about Christianity and its history.
The JW organization as it exists today bears little, if any, resemblance to the same at its start when it was known as the International Bible Students' Association. The IBSA consisted of groups doing independent Bible study and was founded by Charles Taze Russell. After Russell died, "Judge" Franklin Rutherford, an alcoholic psychopath, took over. Rutherford created an expectatation (i.e., false prophecy) that the Old Testament prophets would be resurrected before Armageddon. He had a mansion (called Beth Sarim, Hebrew for something like "House of Princes") built in San Diego, California to house the risen prophets when they came out of their graves. Of course, Rutherford lived in the mansion as Trustee of Abraham, David, and the other Old Testament prophets.
Rutherford also restructured the organization and instituted a hierarchy modeled after the Roman Catholic hierarchy. For every level of RC hierarchy, there is a corresponding JW hierarchical position. When this began, many JW's didn't know which arrangement was "true," and there was a mass exodus of those who wanted to retain the Russell model.
The JW organization is riddled with a history of so much garbage, lies, and human wreckage that it's enough to make you go into clinical depression.
Be kind to your JW buddies because they are deceived. But do some research as recommended by other posters herre and ask good questions.
