Interesting thread. Growing up in Southern California in the 60's, everywhere including the KH was racially diverse. So I don't know anything different. Hispanics, Japanese, black, white made up grade school through high school and the congregation. As a kid we were all friends. It would be interesting to know if there was any racism felt.
I loved the fact as I would run into the older sisters at conventions as a 50+ year old, they would pull me to their chest and still call me "baby girl." But who knows what they and their husbands and kids went through with others at the hall...
I wish I could still talk to some of them, but being "out" makes it too complicated.
