I am not a believer, but I do think there are versions of Christianity that are far less destructive than Jehovah's Witnesses and I think some people need and want religion in their lives, for them there are much better choices. Religion can be something positive, if it helps you to be a better person, if it give you emotional support, a sense of belonging, a community, a moral framework.
The JWs may have gotten a few things right, but they are so wrong in so many other areas they have become a negative, destructive influence in the lives of everyone they touch, in my opinion.
Teaching that you have the only path to salvation is just plain wrong. Of course everyone thinks their own religion is the best, but other religions don't lead you to gleefully look forward to the violent destruction of the majority of mankind, simply because they don't subscribe to a flavor of Christianity. Belonging to a religion that fosters that kind of thinking is to lose a bit of your own humanity, your compassion and your humility. Teaching a literal hell for those not in your select group is just as bad. Many churches do not teach a literal hell.
The Watchtower places too much importance on doctrinal points that they believe only they get correct, when the bible says that the primary way to identify that a group is a true follower of Chtlrist is that they have love among themselves. When was the last time you heard a talk on showing love to others, or helping those in your own congregation? Instead the emphasis is strictly on the preaching work. People going through difficulties are criticized for missing meetings, there is no compassion. Those who miss enough meetings are dropped and shunned, as if they had committed a major sin. Is that love?
The early Christians were allowed to disagree, they were not disfellowshipped for it. They didn't have a rigid, grueling schedule of requirements to meet to gain salvation, they were saved by Christ's sacrifice. They weren't constantly made to feel guilty for minor transgressions or living a normal life. Other religions are not this way. If you miss services for some reason you are welcomed back, not made to feel guilty because you were the victim of difficult circumstances.
Other religions have joyful services, meaningful sermons of a rational length, beautiful music that is uplifting, and enjoyable fellowship. The Jehovah's Witnesses have hours of dry, joyless meetings, mind numbingly boring talks, and rote question and answer sessions where there is only one right answer, the one you are given. No room is made for self expression, for people expressing their individual gifts, for joy. Women are marginalized and given no real voice.
Instead of focusing on doctrine, look for a religion that helps you to be your best self. You could argue doctrine all day long, it won't make you a better person. Look for a group that doesn't force you to ignore scientific fact, there are quite a few of them. There are churches with no doctrine, they just allow you to be a Christian, imagine that. I think that is what religion has to become, if it is to stay meaningful in people's lives. We are not living in bible times, we can't pretend that science hasn't advanced and that we don't know we evolved, we can't pretend women are property anymore. The best religions acknowledge these realities while still trying to meet the spiritual needs of their members.
