Few JWs know how racist, especially anti-Semitic, the WT was in the years leading up to WWII. Rutherfraud attempted to curry favor with Hitler by being ouspokenly anti-Semitic. It's no suprise JWs reflected that same mindset.
Other authors chronicle that JWs were often not the greatest people in their camps, unloving to others and among themselves, with in-fighting and shunning. The quote posted above probably reflects more on individual personalities as to duties, but is reflective of group-think when it came to sheepish subservience.
