On the one hand, good point. But on the other hand, as people note...if I could make my students drop and give me fifty, or wake them up at 4 am to make them run five miles, or call them worthless little feces, or any number of other drill-sergeant-type behaviors not actually within my teacherly authority, it would be a pretty different environment. I am also led to believe from hearing about people's experiences in the military that recruits don't start out good at rule-following; the whole point of basic is to break them so that they can be rebuilt in more conformist, rule-following ways. I think there's compensating machismo in there that appeals to a lot of boys, but I think most girls are too sensible to go in for it ;). Or just don't need to be broken to follow orders.
