You have highlighted a key distinction here, but proceeded to go back to "kids" but I wanted to highlight something that the US HHS found when studying the gender differences between bullying and that is girls tend to experience victimization in the form of sexual harrassment or emotional aggression where as boys were more likely to be victimized physically. Whether nor not this leads credence to any sort of gender theory, or how girls and boys are stereotyped or whatever you want to infer, there are real measurable differences between the type of toxicity found through online bullying or in person bullying, and for girls it does tend to be something emotional (think "ew you're fat, you should just stay home", "ew why are you wearing that", "ew you look like such a pig") versus boys where it tends to be physical threats of violence (think "I'm going to beat your ass", "give me all your lunch money fatty or you'll pay")
