My take on banning the word "bossy":
To me, the real problem is not with the word bossy (which, if "banned", I'm sure would just be replaced with another label equally negative), but with the fact that "by middle school, girls are less interested in leadership roles than boys", which I can see being partially due to the negative reaction when a girl expresses any sign of leadership.
A better campaign would be one that encouraged girls to learn how to 1) be kind and "do unto others as you would have them do unto you" (or "as they would like to have done unto them"); and 2) ignore any criticism that comes from speaking up, being direct, and wanting to lead, when you're following rule #1.
I don't remember being called bossy as a child, but I do remember hearing, when I was in electrical engineering school, jokes about how I was there to find a successful husband, and how I shouldn't apply to an internship in an electrical power company, but rather find a place that was "more appropriate for girls". I entirely ignored these comments and went on to beat the male competition when I applied to one of the rare engineer positions in my city after graduation.http://craigconnects.org/2014/03/why-you-should-ban-bossy.html#comment-9745
