Haha, they like to quote the scripture "the women proclaiming the good news are a large army" to make the ladies feel important at least in some way. But if women are like the army, the men are the sargents, generals etc. Women do the grunt work and but can't "teach" from the stage.
I never had "fun" writing or giving a talk. They don't even let sisters do the part on just reading the bible. Why is that? I guess they want to make sure there is a dividing line from an early age between the sexes. No little girl gets to just stand and read scriptures.
