Easy proof this whole debate is sexist and misogynist af:
1) If girls have to wear bras, why are chubby and larger guys allowed to have their huge man-boobs and nipples flopping out all over the place?
2) If nipples are considered a distraction, why aren't male boners considered a distraction? You legit can see it poking out guy's jeans easily without necessarily looking for it. And before someone says "you're sitting in class" what about the times when students get called up to the board, presenting a project, gym class, walking in the hallways, etc?
A true double standard but people sympathizing with misogyny can continue to do so. Some of you don't even realize how ingrained it is, within your own brain to be misogynist and defend the system that upholds it. But, do you.
