Right. Lemme chip in with some thoughts.
Apart from like one response in this thread, most of the replies here seem to be the byproduct of outrage culture or being mad for the sake of being mad. In the actual context of the scene, the action is depicted as a negative action and one that should be frowned upon. It's a character flaw and not glorified sexism.
Secondly I really dislike the casual diet racist comments here on how it's common in Japan and Japanese media as such with such a sweeping generalization. I thought ERA was better than this. Flaws exist yes, but we shouldn't be fine combing every single damned thing and getting outraged at minor things like these since it ultimately does injustice to actual movements to combat what is a real thing.
Take it easy, people.
