Thin of those white kids screaming at the little black girls coming into their school (under military escort for safety) back in 1957, those white teens spitting on black teens doing soda fountain sit-ins in the 60s… and remember they’re adults now, with kids and even grandkids of their own.
Do you really think they taught their families to be open-hearted and to respect people of color?
This issue is getting better, but it’s got a long way to go yet. Things like this echo through time.
