Racism doesn't stem from birth, it is created from influences and beliefs of narrow minded, terrible modelling influences such as parents, who are spreading their own hate instead of love and compassion onto their children.
This is a quote from an activist named Nelson Mandala. He was someone during this time period who really impacted the Civil Rights era. He changed peoples lives in Little Rock Arkansas for the better. For example, African Americans lives like Liz were improved because earlier in time it was difficult for her and her family members to deal with society but now African Americans are treated more equally.
