Huh? Perhaps you should read what I wrote again, it appears you've completely missed my point. And yes, I read the article, and went to the website, I know what it's about if that's your point.
Here's my point: bossy is not a sexist term, for example it's used to describe poor leaders in environments like the military, where leadership is NOT just men. Acting bossy is bad. Subordinates hate it, and you can't lead by rank alone. It's a damn good lesson.
Therefore, advocating for its banning (the movement is called Ban Bossy after all) is both unwarranted, and entirely unhelpful: because it's a clear unambiguous word that young leaders get" quickly to describe adverse behavior in a leader and it's the proper English use of the word Boss to describe someone acting in a manner like a boss. What word would you use to describe this adverse behavior?
And the "Ban Bossy" movements supposition that it's sexist that it's used to describe "girls" is unsubstantiated. It's a good word to describe behavior, if someone's calling you bossy you need to do some soul searching if you want to be a leader. Don't be a boss, be a leader.
If you're acting bossy, stop and lead instead.
