Well Old Navy after six hours only five people have posted on this thread and I think three of them are women. I doubt very much if this male- dominated forum cares about the role of women in JWs.
I found your link interesting, I had forgotten about Philip's four daughters who were prophetesses in Acts. I vaguely remember the WTS saying something about the gifts of prophecy, speaking in tongues etc that they had in the first century have now passed away so we don't have men or women with gifts of prophecy now. I think that's the limp argument they used to treat women as second class citizens.
As Diogenesister pointed out how can Paul's 'I do not permit a woman to speak' be applied to holding a microphone. For that matter how can it be applied to being a literature servant?
