Sexualizing highschool girls

Over the past couple of weeks i have noticed that a lot of staff are dress coding the females at my school more then males. Part of our dress code is that you can't wear shorts or have holes more then 3 inches above the knee and with that the girls that wear ripped jeans always have then patched up by parents or the school makes them duct tape them closed but the boys i always see them with shorts that are for sure more then 3 inches above the knee and the staff are always like "oh they're tall so they can't help it" Well hun i'm a 6 foot tall female and anytime i wear shorts that could be like a milimeter above 3 inches over my knee you're freaking out because you can see my thighs but when you see the boys with short shorts and their dicks swinging you don't say a word. I once seen this girl with a top on and when she raised her hand to answer a question and her stomach barely showed and she instantly was sent to the office. Again i'm so sorry for ranting but my school really needs help (i'll keep you updated on this story)
