Hi, and welcome to JWN!
1. if jw isn't the right religion, then which one is? Or is it basically believe in God, the bible and you'll be fine?
Is it possible that no religion is "right?" That they all reflects the beliefs, fears and ambitions of the people who created the religions? I find it very compelling that people tend to believe the religion they were born in is the true religion. So if you had been born to a Buddhist family, you'd believe that Buddhism is right. They can't all be right, and when you look at the doctrines and practices, it becomes clear that none of them are right.
2. i can't find any other religion who has broken thru all the racial barriers and teach the same stuff worldwide....In all honesty I do trust "most" jw if I were to stay at their house or vice versa.
You may not have experienced or observed racism in the wtbts; that doesn't mean it isn't there. The congregation I grew up in was racially mixed and we weren't raised to think that people of different skin colors or ethnic backgrounds were in any way inferior. That didn't keep the congregations in La Jolla from feeling superior to us, because of our mixed race congregation and general poverty.
3. If some of you don't believe in the organization, why attack it or stand outside assemblies etc trying to spread the word of being against them, what benefit is this?
Well, I don't personally see much benefit to standing outside the assemblies trying with signs. I remember as a kid how we were told they were apostates, and they had some name for apostates that I've forgotten, evil something class. However, I totally understand people who are driven to speak out against the wtbts, and who want to demonstrate against it.
4. I have read and seen throughout history that they could have wrong teachings and that yes they have been wrong in the past about some things, jw normally say well we changed and the light got brighter.
Well, it's illogical bullshit. How could something be completely true at one time, and then later something diametrically opposite now be true, when they've always claimed that they have the definitive truth. "The light is getting brighter," is a thought-stopping sentence that keeps them from questioning anything.
Best thing is to keep researching, asking questions, looking for different ideas and testing them against what you know and what you learn. But don't speak up too much until you are really ready, because they can make life hard for you if you want to keep friends and family from shunning you.
