The overall presentation and the images within this pin represent "gestalt" by symmetry. The gestalt concept says that objects must be balanced or symmetrical in order to be seen as complete or whole. Not only are the images symmetrical, but the presentation is as well.
Women are often shamed for dressing in shorts or tank tops, however men are allowed to go outside without even wearing shirts. This is ridiculous. This was posted in a school in protest of the dress code. The caption of the pin read "Shaming Girls For Their Bodies v, Teaching Men Responsibility. You don't have to be a rocket scientist to figure out which option is the correct one." I agree totally.
