@Elorm: Hello, and welcome to this forum. I can see you weren't too pleased with some of our comments on here. It really helps to be "in the know" about JWs, because everyone on this forum considers the religion to be a harmful cult. Our anger is not because we don't want JW kids to dedicate our lives to God, we just don't want them dedicating their lives to this religious organization. Actually, they ask us questions at baptism and one of them asks us if we are being baptized in the name of Jehovah (the father), his son (Jesus), and the SPIRIT-DIRECTED ORGANIZATION. So, it's quite a contract there.
Some background knowledge you may not be aware of: the Jehovah's Witnesses are a "we're the only true way" kind of religion, they are fundamentalists, they isolate members from the outside world (it's supposed to be destroyed at armageddon, and only JWs will survive God's wrath), they believe all other religions (and the world's governments) are unwittingly under Satan's control, so certain things happen when you become baptized as a JW. If you choose to leave the religion (especially if you leave to become a different kind of Christian; for some reason, the other Christian groups in the world are demonized more often than any other major religious classification), you are subject to a shunning practice, wherein the defector is considered a bad person and, more often than not, are completely cut off from having all contact with friends and family who are still active JW. In fact, that's why so many of us are members of this forum. Many of us got baptized, left, and were shunned. This forum is the place we go to for healing after that.
And, for your other questions, yes, some of us are still Christians, and others are Atheists (like yours truly), some of us are between the two, some of us belong to completely different belief systems unlike the previously mentioned.
