Welcome to the forum scrapmama777 and thank you for sharing your story!
The WTS never elaborates on what exactly people that leave disagree with; they actively discourage independent investigation and demonise any alternative views.
I never gave this much thought as I thought that the "truth" can stand up to anything thrown up against it.
Over 12 months ago I started to investigate opposing views - a post that had a profound impact on me was this thread by a serving elder at the time

Please continue to keep an open mind and I look forward to more of your posts.
Best wishes
