"The first is that it seems to suggest that "power" is something given by others or granted by society."
You're kidding right?
"Supreme executive power derives from a mandate from the masses..." - Dennis
Power is absolutely granted by society. It may not be the only path to power, but society itself has an overwhelming power and often grants that power to a figurehead. In the case of this subject matter men are often considered more powerful, more rational, and better than women... which both detracts from their complaints AND puts them in positions where a man can exert his will despite her wishes.
To whit: Have you ever just been feeling like shit, and not wanted anyone to see you that way? No imagine people, absolutely everyone around you, stared at you anyway. This is what women deal with... except for the added threat that they are physically weaker than the people staring, and would most likely be unable to defend themselves if they decided to move on from simple staring.
"Power can be taken, but not given. The process of the taking is empowerment in itself." --Gloria Steinem
In making this statement, Gloria was repeating a common aphorism, and it's an aphorism for a reason--because it's true.
You seem to confuse power with leadership or influence. Power confers leadership and influence. Leadership and influence does not confer power. One cannot be a leader without first being powerful--without first having the physical and mental constitution capable of sustaining the burdens of leadership.
Power is ultimately about self-mastery. Anyone who has mastered the self is powerful. So much so that the empowered hermit master is a mythical archetype--Jesus, Buddha, Yoda, Obi Wan Kenobi, etc.
So, society doesn't grant power. Society grants leadership. And except for corrupt systems, it grants leadership only to the powerful.
"One cannot be a leader without first being powerful--without first having the physical and mental constitution capable of sustaining the burdens of leadership."
Tell that to anyone with a terrible middle manager. Or anyone watching Trump blunder his way into the front running for the GOP. Or to these 11 rules crowned while they were still in diapers: http://mentalfloss.com/article/12252/11-monarchs-crowned-while-they-were-diapers
There's really no shortage of rulers throughout history who absolutely had power, yet were not physically or mentally capable of handling it. These usually create the worst atrocities in history.
So yes, society absolutely does grant power. Power can also be taken, however usually society resents that and works against it.
