No sensible person considers that the NAIA has anything to do with "higher levels of sport," even if one were to accept your horribly transphobic argument about the nature of women. People who are drawn to "higher levels of sport" attend large colleges and universities that are part of the NCAA. NAIA sporting programs, despite my earlier misuse of the term intramural, are for all practical purposes, recreational. No NAIA student athlete is aiming for "higher levels of sport" or they wouldn't be attending an NAIA college.
