It's funny but "bully" is more associated with males and "bossy" with females. Both have negative connotations of forcing someone to do something against their own will. It seems that the reason behind not banning "bossy" is that females require this opportunity for leadership development. It seems sexist that females should be allowed to impose their will on others but males shouldn't in similar situations. I would argue that females already have a leg up on their male counterparts with the fact that they mature earlier during adolescence and perhaps use this to their advantage. As the article mentions, other ways exist to exhibit leadership. Being bossy though is the worst alignment of incentives: power & peer acceptance thru fear vs respect.
