The average naïve pro-Nazi individual in 20th century Europe probably enjoyed certain personal perks & benefits, and may have even transformed into a more disciplined person as a result of the ideology; yet any such personal betterment is blemished by crimes of the broader organisation and its leadership.
Did you honestly just compare the JWs to being nazis? Such a ridiculous claim. Totally unbalanced and unobjective.
The vast majority of JWs are there because they want to be good people, try to be good people, and I think are more law-abiding on average and certainly don't go around committing war-crimes.
These kind of comparison-claims just make us look like nutters.
