Thank you so much for sharing. I'm sure that like you, there are others lurking and reading and maybe thinking critically for the first time in their lives.
All the times I used to cringe when someone on this site would say that they are a cult, I thought, no, don't have to go that far. But now after 4 years I have nothing to say but yes, if you study the whole religion and really pay attention to everything, you too will see that they are indeed a cult.
This, in my experience, has been a rather common occurrence, and not only with JWs, but with the public in general. There are many misconceptions about what cults are, so many people react when they use that label to identify any group that they belong.
I'd suggest to research more about those groups and how they are, as there are different types of cults, there are different levels of harm that they cause, and there are also different types of things that people have to recover from. That can help you gain more perspective (that is, if you still need to).
