I sometimes reflect on pride in being a member of the White race.
I know such thoughts aren't considered PC the way saying "Black Pride" or "Latino Pride" is, but I think it's kind of cool that I share a similar heritage with the inventors of calculus or linear algebra or the transistor.
I think it depends how you use it. Ultimately, all pride other than human pride and pride in yourself is bullshit. But if taking pride in people who share a superficial similarity with you helps with motivation, and you do so with full awareness that it's just a cognitive trick, and ultimately bullshit, there's nothing wrong with it.
Human pride is pretty bullshit too.
That being said, your frustration is misplaced. Instead of incorrectly spinning a legacy of slavery into a positive attribute, understand that there were some events that set minorities down negative paths that have repercussions to this day.
Rest assured that everyone in America knows the myriad of positive things that white people do. But, as they are minorities, other races don't have the outlet for such positive slants.
