The spark for me started off when a JW friend of mine tipped me about the Wrong dates of 607 BC. Satanic flood gates opened when I did my own research on the Internet.
When I read about the UNO connection, 100% realized how I had been fooled. Stopped attending meeting by then.
Totally it took about 4 months to realize that I was in a CULT. Disassociated a year later.
