Yes I agree it is very damaging to children. The basic idea that your parents don't love you just for being their child does lasting harm. I would do anything for my daughter, she knows this. She has grown up stronger than I did because of it.
The judgemental way we are taught to look at other people is also harmful. It stops you seeing individuals with all their good, bad, interesting and quirky qualities.
People are fun, sometimes they drive you crazy but generally when the chips are down, most people you know would be there for you. They aren't a faceless mass of bad people who deserve to die.
I just want to add it's taken me a ridiculously long time to understand people because of my JW upbringing. I'm inclined to give up on people because of my childhood beliefs. Also because my family are like brick walls, there's no getting through to them, I tend to see other people like that.
I think that's it, that's the end of the friendship because we had a slight falling out. However if I try again they are fine! They've either forgotten all about it or they want me to forgive them! Who knew friends could be like this! I'm still learning, my daughter learned all this at primary school because she was allowed to have friends. It's taken me so long. Better late than never.
