I have never met Alice Walker, but I was influenced by her poetry and fiction way back in high school, and I love her non-fiction and activism, too.
Here is a brief essay that she wrote for the Middle East Children's Alliance:
Empathy is a Wave: The Banning of Palestinian Children's Art (From the Museum of Children's Art in Oakland)
The Good News is that the Exhibit will take place tomorrow!
" Empathy is a wave that need never be stopped." ~ Alice Walker, 2011
