Man...nobody said that when I was in high school (30 years ago). Times have changed.
Either way it seems like speculation, maybe it should be presented as such instead of stating it as fact?
I don't believe these anecdotes reflect reality, and I don't think they really bring anything of substance to the conversation. It's borderline alarmist at best.
Tbf 30 years ago fights seemed common whereas there were very few when I was in school. Seems like physical violence has evolved into verbal because it's harder to trace and punish. (Just a guess)
