Right now we'll take just about any thug with a high school diploma. So, now we have all these women and people whine about gender-norming of PT standards. There is a distinction between physical fitness and physical ability. The military requires its people to be physically fit according to their age and gender. Physically fit means you're healthy enough to get out of your own way and you won't die of a heart attack while driving the colonel to the golf course.
Some jobs also require a level of physical ability.
There is no discrimination in having an absolute standard of physical ability to be a SEAL while maintaining a gender matched set of standards for retention in the Navy. So no problem. People have been getting laid at the wrong times in wrong the places for as long as people have been getting laid. Full integration of women into all jobs will bring with it some problems. But the failure to deliver equal treatment is at the heart of most of the gender related problems we're having now.
