Missing the point still. Everything done by the person on the downside of a power gap is done in the context of the predicted consequences for doing otherwise. This is a sexist society, full of such concepts as "humourless ice bitch". Actually showing a discomfort which is felt inside might be dangerous. A room entirely full of women is enough to counterbalance this and allow communal frowns to speak loudly. Merely "explicitly giv[ing] the woman room to speak up" is liable to get a response that means "don't hate me" more than it means "here is what I honestly feel". Power has to work harder to blunt its bad effects than just saying "so please ignore the power gap".
