Yes, exactly. Everybody saying "but you're not supposed to resist muggers" is missing the point. If you get mugged by the same person 47 times in a row, you're not going to keep getting that advice. A one-off incident at school which goes unpunished is troubling but understandable. It's the repeated long-term bullying that gets nothing but shrugs and "ignore it and it'll go away" that is completely nuts.
