Modesty standards are not oppressive
When I was in high school, several students were told to remove the neon shoelaces they had purchased for their basketball shoes back to the laces that came with the shoes. We were not to draw attention to ourselves, and the neon laces were meant to attract attention. Coming from this background, I find the "controversy" about telling middle school girls not to wear leggings as pants to be absolutely absurd.
One set of "parents" even sent a letter to the school saying the ban contributes to "rape culture." This kind of absurd hysteria borders on child abuse. No one is saying that girls who wear leggings as pants "deserve" to be violently attacked, or that criminals are somehow less responsible for their actions. Furthermore, we are talking about middle school boys here. Feminists are only discrediting themselves by using rhetoric that portrays children as sexual monsters because they are distracted by inappropriate clothing.
The issue is not oppression of girls and it certainly is not "rape culture." The issue is basic modesty standards and not creating a distracting environment for students. The issue is having children attend school dressed in a way that they are prepared to learn and not prevent others from learning. This is not oppressive to either boys or girls. It is the same as telling students they may not wear green Mohawks.
The problem here is a small example of the overall problem created by our culture's hatred of authority and irresponsible "parents" more interested in being their child's friend than being mothers and fathers. It is pathetic and irresponsible.
