I was raised in the organization and while growing up, all the attention of the WWII was focused on the persecution the JW suffered at the hands of the Nazis for their faith. It seemed to me that everyone else who died at the hand of the nazis was meaningless as the JWs were the only one who died for their faith. It also brought me to believe that the number of JW victims was much higher than what it truly was.
Then, about five years ago, I visited the camp of Auschwitz and looked further into what happened. What struck me was the millions of people who fought against the Nazis and helped the resistance. A great majority of them were believing Catholics. Unlike the JWs, they'd say hi Hitler and than go blow up some railway.
When I realized this, I was horrified by the fact that JWs are basically ignoring the stories of all those heroes from other faith. Instead, they blame the other faiths by pointing to those who did bad things while ignoring that about a third of the JWs in Germany actually became inactive.
