Crash:If race is not scientifically based, what is it based on?

Some characteristics that our Society uses to define race is; color of your skin, and religon. Most of the time Society defines our race by what color we are but occasionally you will here a "white" person refer to there race as Jewish. A scene that refer's to race is when that cop gets in an argument with that lady because, he's mad he can't help his dad after his dad lost everything for protecting and helping out "her people". He refers to her people as her race and he is defining her race as African American. I don't think ever in my life (until this class) race has been something different than the color of someone's skin.
