This may have to do more with what your parents were like, and not necessarily if you were raised by Jehovah's Witnesses.
I was originally raised by non-religious parents of Jewish ancestry. Besides for a few cultural earmarks, there was little religion. We were a wealthy family, with all the material things you can imagine. My parents celebrated Christmas and Halloween and birthdays (things you don't always find in a every Jewish home). My grandparents gave me what little teaching in Jewish ways as they could, and their influence was great, but the home my parents raised me in was very different.
My parents were also abusive. I had to be rescued and separated from my parents who put my life in physical danger repeatedly since infancy. I have both emotional and physical scars from the little over 10 years I was with them.
My aunt (of no blood relation) raised me after that. She was a Jehovah's Witness. She was kind, loving, caring, thoughtful, honest and dependable. She went to every meeting, assembly and convention, and was even a regular pioneer for some time. I went along to every meeting as well and out in service regularly. I didn't have what I had grown up with materially and had no Christmas or birthday celebrations anymore, but I also had peace, love, and no more abuse at home.
So it depends. The way my aunt practiced her religion was very orderly and exemplary, and this included how she treated me and her children, my cousins. It was a loving home, and from what I saw even then a lot better than even others had it who were also JWs. Some of them had what some here are describing.
And that is because abusive parents come in all denominations (and even without being religious, like mine). So some born into the religion experienced the Watchtower through an abusive environment. Others did not. But just as not all non-religious parents are abusers like my non-religious parents, not all JW families were the same either.
Being raised in a religious home can be abusive IF the parents use the religion as one of their tools of abuse. I've seen this in Catholic and Jewish and Mormon and JW homes. But my parents once beat me with a toy, and that doesn't mean that all children who are given toys will experience being bruised and bloodied by them as I was.
We can all be so greatly limited by our personal experience with the Witnesses that we often cannot see that our own view of Witness life may be unique. If you were abused growing up, you might want to blame the religion before you blame your parents. Being an adult survivor of child abuse, I see this all the time.
If you had an abusive childhood it is because you had abusive parents. A religion can play a part, true, but it can't raise you irresponsibly. Parents can however, and do. A religion can make demands and tell a parent to treat their child one way, and the parent can always say, "No." My aunt did this several times. In the 1970s she made sure all her kids were immunized and took medications when they needed it. She was a nurse, but the Witnesses sometimes frowned on medicine back then (just see the old "Youth" book from my era). My aunt had no problem putting elders and other mothers in their place when they challenged her on this.
If your JW parents did everything by the book, then you may have received some religious abuse that way. But your parents had the option of being brave like my aunt and saying "no." So it all can't be blamed on the religion. My aunt is a second-generation JW too, and she knew the difference between good parenting and going along with the Watchtower blindly.
I was abused by non-religious parents. You may have been abused by religious parents. The constant here? Abusive parents.
Besides, Jewish kids grow up without Christmas, some without birthday celebrations, and some with strict religious-adhering parents...and I know many like this, none of whom claim it was abuse.
Child abuse knows no religion. It comes from people who abuse children, period. So again if you were abused growing up, the Watchtower might have had some fault in it, but you need to take a hard and honest look at your parents too.
