Yes alanv, and as a born in, I was brought up with the attitude we were all humans and equal before god. Because my parents were unusual in their attitude to people from other ethnic groups and cultures, even before they became J.W's, our Home was " Open House" to all sorts of people, from different backgrounds, and different politics even.
Because of benefiting from these aspects of my upbringing, I could never have become a Racist ! As you rightly say this is one thing we can praise JW's for.
It became clear to me thinking on this matter, that until I was about 10 I was not even aware of Racism, growing up in a White Rural Community. Then one day I was standing in a Field with a friend, and two farm workers were passing, standing up in the back of a pick-up truck, and they remarked " Yea, West African", they were wrong about her ethnicity, but I became aware they thought of her as a mere specimen, like an animal in a Zoo, to gawp at, and show no respect. I was hurt and shocked.
So Racism was there in my little Community, but I had not experienced it in action in my life before. I have always hated Racism in any form ever since.
