<I am not racist/prejudice because...>
No one else on here has heard this expression before?
Okay let us take what you said and compare to other examples. I am not taking this out of context. I am discussing the way you set up the OP.
This follows the classic saying "I am not racist because I have a (insert minority here) friend."
Here are some other examples for your viewing pleasure:
I am not racist/prejudice because... or Anyway, I can't be racist/prejudice because...
1. My grandfather/relative was from (country).
2. My boyfriend/girlfriend is (insert minority here).
3. I hate everybody or I hate all races equally.
4. I said so.
5. I am not even white.
6. I vote Democrat or I voted Obama.
7. I'm majoring in Liberal Arts.
8. Racism is a crime, and crime is for (insert race here).
Does this make it any more clear?
