Welcome to the forum! There are some that left the organization who are bitter and hate-filled and make it their life's mission to bring down WTS. They actually help the WT's cause because they fulfill exactly what the organization says about them. You'll find on this forum all kinds of people who have left, are currently JWs (like myself), or have family involved in the WTS. "Apostates" are not all the same - we are different people with different experiences and feelings like everyone else. Of course there are good things about Jehovah's Witnesses and there are many wonderful people in the organization. But you yourself said you've been turned off by the blood issue and the shunning. Those are major issues and something that the Governing Body has not been willing to bend on.
I am afraid of my family and friends shunning me if they find out I don't except all Witness teachings. I come onto this forum to talk with people who understand what I'm going through. I cannot talk to anyone about my feelings because as soon as I do I'll be asked if I believe we have "the truth". If I answer negatively, all hell will break loose. Everyone I love will immediately distrust me and shun me. Trust me. I've seen it happen with my own eyes. AS A BAPTIZED WITNESS, YOU CANNOT QUESTION THE GOVERNING BODY. You will be labelled. There will be consequences. The group think is intense and they are terrified of anything that even remotely resembles independent thinking. As someone who is not yet baptized, you're seeing all the good aspects of the group and of course, you won't be exposed to as much of the close-minded mentality since you are an interested one and they want you to come "into the truth". I love the vast majority of my brothers and sisters, but I've come to recognize that this organization has some major problems and has covered up a lot to portray themselves as God's spokesmen on earth.
Do your due diligence. By all means, look at all the evidence. Ask yourself, are all these people who "apostasized" really on the Devil's side or is there more to the story? There is much more to the story than meets the eye. If you find that becoming a Witness makes you happy, go for it. One day, though, you might realize that you feel like you're running on a hamster wheel of theocratic activity with no honorable way to get off.
