I can't speak for white people because I am not. But certainly Hispanic congregations don't fit the lack of fun and love that are often described here by some posters. The Hispanic JW's are sincere, very friendly and loving. They love music and dancing. They laugh easily. Also, Hispanics are not very good at observing shunning rules either, especially with close relatives. So, to some degree, I confirm the opening comment
So what may be the difference between white and non-white. White seems more cold and rational, non-white seems more warm and emotional. Where do I fit?: the cold and rational, but brown.
