Ok I get that they were mostly military cadets when their University started just like MSU was hence the Drill Field. And did not have female students or female students living on campus for a while.
But once MSU finally got female co-eds, they became the cheerleaders and God bless we were happy because we had certainly been missing them.
But A&M just kept their male cheerleaders (permanently for football) because apparently they had "adjusted" to the all male routine, just like a guy who goes away to prison might "adjust" to the all male routine.
