Would it be helpful to humano or any routinely oppressed person to get rid of the prejudice against their oppressor they may have, when walking into a situation with their oppressor where it is indeed likely that their oppressor may act as they have done routinely and habitually, and oppress them?

Am I using the word "oppress" too much here?

It is reasonable to assume that, if a person or people of color has/have a prejudice, as you call it, against white people, the prejudice is as a result of poor treatment by that culture (which we can just call the DWC or Dominant White Culture for short). Humanodon has implied or stated that here.

In that case, how does it behoove humanodon to walk into a situation deliberately ignoring his feelings, which are caused by repeated first-hand experience, that it may not be safe for him there? If I have been repeatedly victimized by men in my life, I may be very careful about which men I choose to spend time with going forward. I may refuse to leave bars with strange men or be alone with them. That can be construed as a prejudice. But let's say that I've been sexually harassed or abused three times when I left bars with strange men or was alone with them. Is it smart to say "Well, I just have a natural prejudice against men because of my experiences. I acknowledge it, and now I'm going to refuse to judge other men based on this treatment, and continue to leave bars with strange men or be alone with them." Is that a smart thing for me to do?
