I would use the term 'strong female leader', though. She's unafraid to speak her mind, and tells a class of people who are being pushed against right here in the good ol' US of A that what they feel is natural, acceptable, and they have every right to human equality as every one else.
WHich is nothing else, makes her culturally irrelevant to me.
Again I ask you
"Or do you mean "heroic" but only within their own country/ culture/society? Not, say, the English speaking world at large? Or only to a particular age/ ethnic/ gender demographic? "
I still don't see how she is a leader. Julia Gillard or Anna Bligh are leaders.
