I grew up in the once segregated South. I experienced forced integration during my formative school years. I lived the sacrifices, burdens, and tears. I also lived the moments of understanding, of acknowledgment, of fellowship and success. I saw my parents and grandparents coming home beaten down - and some of my friends beaten up.
