Of course, let's ignore the fact that the video is set to be public because the teacher is required to hand in the homework. These arguments of "the video is already public, where did it leak out?" are descriptions of objective facts, but what really makes it sour is actually being forwarded. This behavior in the Jinba Club and other sex clubs—starts here: it is no longer "yoga homework in gym class", but a plaything for the male gaze. Here, women are just symbols to vent their desires and convey fun.
Teacher Chizuru Ueno mentioned in the book Misogyny: "The concept of "female hatred by lecherous men" is like Pavlov's dog. Women's bodies, movements and images are violently condensed into a "female symbol" and vent their desires, even photo retouching service if this is just a sports video demonstrating yoga movements. This can be observed from the uncomfortable sexually harassing comments and likes, and what is even more cruel is that they are fully aware that they are arrogantly dominating the viewing power of the male gaze, and take it for granted.
Among those video links, because one of the victims posted his own IG link in the comment area at the bottom of the video, "maybe directly and seamlessly become an Internet celebrity", "the parties are happy and want to increase their fans, you guys. What are people escorting?" This kind of remarks followed, no doubt, is the best proof of this kind of point of view. Compared with the simple male gaze and female hatred, what is more frightening is the existence of a group, organized and standardized society such as the hegemony.
