Having been a female mid long ago when things were much worse, the comments about today don't surprise me. In my day, we got ragged not only for weight issues (before TPTB realized that women cannot consume 6,000 calories a day and maintain their trim figures no matter how much they work out) but also accused of taking the place of a "warrior" male -- in the days when women weren't allowed in combat.
It's rather sad, but no institution changes overnight or, in this case, in 35 years. Trust me, if the PT standards were identical (which would be unfair to women), those who have issues with women would find some other reason to vent. Those people won't change. And, quite honestly, they exist in the private sector/business world as well. In some cases, it can be worse -- maybe not in college but in the workplace.
The environment for women at USNA is going to be different from a civilian college. But there are huge benefits in the process -- many of which you don't realize/understand until years later. As tough as the experience was, I wouldn't have traded it for the civilian college life.
Finally, I found "the Fleet" to be very different. In my squadron, where I was the only female officer, the guys treated me like a sister. They were great. Maybe it was because some of the "boys" had grown into men. Who knows?
