I believe this does fall under the category of manure-stirring. Way to go.
I do think as you move up to the older levels, the play is different. I believe the saying is, "Girls play horizontal, boys play vertical". Some officials decide they want to do one or the other, so they don't have to adapt to a different game every night. Many people also feel that the boy's game is the "better", or more prestigious game, and the girl's game is harder to call. Therefore, assignors and AD's are more willing to assign those "better" games to the "better" officials. Around our area, most of the schools hire their own officials; we have very few assignors at the HS level. So most of the time, officials work both for a school, unless an official specifically states they will only work boys or girls.
