the mere fact a Witness of 50 years can still think it's OK to say such a thing says loads about the way the WTS "teaches"
If you were to give my mother a quiz about elementary WT doctrines, I doubt she'd get half of the answers right. In fact, I'm quite certain she would have no idea whether according to WT doctrine the dinosaurs were wiped out by the flood or died off many years before. She simply doesn't care about that kind of thing. She's been a baptized Witness for something like 30 years. I have no idea how she "passed" the question sessions she had with the elders before her baptism.
What's worse, my dad to this day says he expected to see the holy spirit or a vision after being dunked. It's a crazy world. All my mom cared about were that the children were well dressed and well behaved and she wanted to raise her own kids in that environment. My dad was excited that he finally had access to the Bible (he was Catholic) and could now argue with his siblings and "prove" them wrong using the Bible. That was a huge deal. When he was growing up only priests dared attempt to understand the Bible.
