Comment on someone's dismissive attitude towards high school students and issue a warning about confronting other people's children.
So in your view high school kids are stupid then. No possible way for them to have an opinion that's valid, right? Many of the views I have today were developed during those years. To be so dismissive says a lot about you and how you value youth. And I'll provide a fair warning to you: I'd tread very carefully when confronting other peoples children at sporting events. That's a great way to get punched in the mouth. Your whole statement wreaks of coded racism and ageism.
