Great topic. Never a JW, I have always wondered how and when the JWS made this transition? I grew up in the US during the transition my high school years were 1. 10th grade all white 2. 11th grade you had a choice of school so bussing started on a limited basis 3.12th grade mandatory bussing so they achieved a 50/50 ratio.
So this switch in attitude toward the separation of the black/white/Hispanic congregations and thus a merging should have taken place sometime around the 60's or maybe into the 70's?
Which then leads to my next question if the WT eventually caved into societies view of equality of racial differences then why have they stood so firm on women being the under dog and staying in submission to men?
Along the way many other churches have recognized the value of women in the church and have made them Elders or Ministers, they basically are reading the same Bible.
