Diogenesister, I agree with you that everything revealed about women at Bethel seems very "fuzzy", like it's a bit of a grey area. When they started allowing married couples into Bethel, I suppose the women had the traditionally "domestic" roles, or "privileges" foisted on them. Single sisters with qualifications must have presented a conundrum. I bet they were watched as by a hawk.
I can't imagine an institution organised along such business-like lines as the WT didn't have detailed operations manuals. It would be interesting to see how those treated women at Bethel. Have any such operations manuals been leaked?
