Regarding the subject of changing attitudes :
There is a wonderful song in "South Pacific" about how bigotry is passed on. It's called "You've Got To Be Carefully Taught" if memory serves.
Perhaps some Board member with a better memory or a collection of Original Cast recordings could dig out the words and post them ????
It stands alone as a poem, set to music it is very poignant.

Read this somewhere ... wish it was a bumper sticker!
"Bigotry is a disease, don't be a carrier"

wow
