I'm not necessarily asking for the big stumbling blocks here or things you discovered once you started doing your own research outside the borg. I'm talking about the smaller things.
For me one thing was the talk of no one being able to become a witness unless "Jehovahs drew them to him". As a born-in this never jived with me. The other issue was if I had been born on the other side of the world I would likely be wearing a burkha, or otherwise brought up in another type of religion with little or no chance of coming into contact with "the truth".
How about you?
