It's usually the case with born ins, or those raised as a kid in "the truthâ„¢", when it comes to doing something religious they blindly pick the Watchtower because that's what they knew as a kid as religion. The same thing happened when Michael Jackson died. Paris Jackson was going into a KH carrying the old brown covered songbook. Since when did Michael and/or his kids attend a KH?
It's no different from the "catholic" friends i have. They know very little about the religion but they're "catholic" because they were born into it as a kid. Only ever go to church for weddings and funerals.
