My heart goes out to all who face racism in one way or another. My dad was very prejudiced, which I always found surprising considering that he was an immigrant himself, often subject to discrimination. It hurt me terribly when he was rude to my friends or boyfriends who were of another race or ethnic background, and was a big source of contention in my relationship with my dad.
