I actually agree with what was printed by the society there. One has to remember that those were printed nearly 43 years ago. At the time they reflected the countries point of view at the moment. Civil Rights have made great strides since the last 40 years. At least where I live in Southern California racial predjudice is certainly not THAT popular. My nephews are half-black. My ex-brother-in law is black. I don't ever remember there being an issue with the marriage or with the children by either my family or people around us.
Of course I stayed in Kentucky for a few months. My aunt who is in her 80s made a comment once about being 'shocked to see 'nigger' in the Walmart parking lot.' Her grandson, my cousin, came to stay with me the following summer, and fell madly in love with a "colored" girl, one of my best friends.
p.s. they aren't JWs either.
