You are wrong. Feminism as a broad social movement, and as an academic discipline, explicitly sought to question and attack the social structures and behaviors that were often insisted to be "innate" about female psychology and well being. Basically no one would find that offensive today. It's profoundly mainstream.
Many more people would find it offensive to imply that social media addiction, or that an increasing trend of suicidal ideation as a result of social media use, is somehow a result of femaleness tout-court. That's downright archaic.
Social media companies take advantage of the ways women are socialized into an incredible and unnecessary focus on their bodies by pouring rocket fuel on it.
