I don't know either. It's obvious that (most) kids 'see' race differently than we (old timers?) do.
And we know race, or at least culture, makes a difference. The Asians and their faulty armour have a higher overall IQ than us pinkish pale people do.
I also see a good natured rivally down in the financially challenged areas. I'm uncertain that it's bad. It seems like a comradre thing.
Btw, I have a hard time believing you go around insulting people all the time. It's a great Lent issue. Wearing purple?
