Yes. I understand. Prejudice is a more general term, one which encompasses several ugly "isms," including racism. Racism, like you say, is based on trivial, "skin-deep" issues. The unique individual is discarded all together and given some generic, stereotype-based set of attributes. So, it's like a "you've met one, then you've met them all" line of thought.
Forgive my use of the term "racism." Prejudice is a better word, but racism IS a specific form of prejudice.
Hostility and feelings of hatred are real, and it's not my place to tell minorities that their frustrations are unwarranted or their anger misplaced. In many cases, it certainly isn't. I only know that, no matter race, color, creed and unique life circumstances, hate will never solve our problems or make our lives better. It will only fester and cause greater misery.
But hey, I don't have all the answers. One man's perspective is limited.
