Personally, I prefer to quote my parents approach to teaching myself and my siblings about racism. First, racism is just one (of many) forms of predjudice- something we all have.
Also, we must understand that predjudice comes from ignorance (whether voluntary or involuntary); and ignorance can easily be defined as a lack of understanding.
We all have ignorance on some topic or another. That will never change as a whole; but we can change individually by making the effort to better inform ourselves on things we don't understand. We really need (as a nation) to stop allowing ourselves to hate what we do not fully understand.
That's why I prefer to use the word "dislike". By accepting hate, we tell ourselves that we won't even make the effort to understand what we previously did not. Admitting that we dislike something or even someone leaves us our humanity and allows for that change that signals progress.
