The thing is, more women sitting like men requires some men to sit more like women. It requires attention to someone else’s personal space. And more deeply, it requires a perspective shift: that no person inherently deserves to have a larger psychological piece of the universe than another person. Your wingspan might be wider, for example, but your comfort shouldn’t indifferently come at the expense of someone else’s.
Devil’s advocate. Let’s assume that ‘more women sitting like men requires more men sit like women.’ Wouldm’t more women sitting like men provoke exactly that? And if less women got out of men’s way on the street, wouldn’t it be more likely to occur to them that they might bump into someone?
