My immediate reaction to that was no different from my immediate reaction to the logically equivalent “We should not be satisfied until approximately one in two children permanently excluded from school is a boy.” Perhaps I’m just too logical.
I don’t know if your comment was intended seriously but you do raise a serious point. Why are three times as many boys as girls permanently excluded from school? Do boys offend at three times the rate of girls? Not in my experience. Girls are every bit as badly behaved as boys but there has always been a tendency to play down girls’ misbehaviour. Admitting girls commit offences serious enough to warrant expulsion challenges the view that they’re all “Sugar and Spice”. Furthermore, when misbehaviour by girls is seen in the same way as that of boys, overall misbehaviour levels appear to approximately double.
