She said she asked her big sister about her experiences with racism as a child, especially when she wasn't accompanied by their parents, and became \"very angry\" after hearing her Meg's blunt reply.

\"I was raised with adoption, looking beyond skin color was the norm for me, and I just believed that love is love -- it doesn't matter what we look like,\" Heigl explained. \"But then when I asked my sister, Meg, if she had been treated one way when she was out in public with our parents and a different way when she was out by herself without them, she said, 'Oh yeah, all the time!'\"

She said she realized she \"had been so naive.\"

\"I had to calm down and realize, 'OK, this isn't about how it makes me feel. It's about how I need to protect my daughters and prepare them for the world,'\" the actress told the outlet. \"Because I can't change society in one fell swoop.\"
