To me, racism is hatred toward a person or persons because of their race, the desire to cause pain or suffering to a group of people because of their race, or actively trying to rid the world of a race of people.
All humans are biased to some degree or another. And we are all biased for different reasons. If I am hiring people, there's a strong likelihood that I am going to be biased about who I hire based on where they grew up, where they went to school, what ethnicity they are, what gender they are, what race they are, simply because I am human.
These do not equate to hatred which I think is what racism is about. Eqaulity is a noble objective in some ways but ridding the world of human bias is not going to happen.
