It's frustrating I know. I was discouraged from going to university because they were having sex in the corridors! My mother was like yours, blind as to how the world works and she wanted to keep her kids naive too.
JWs are taught the world is a terrible place full of immoral, vile people. It's cult indoctrination to keep them from finding out about normal life or educating their children. As surely as night follows day education will mean the kids realising they're in a cult and the leaders don't want that.
Hang in there and keep posting here. It's good to vent but please could you try writing in paragraphs? It's a little hard to read without them. Thanks.
