Much like how jews still hate Christians despite Christians apparently saving them from annihilation; blacks hate Whites despite Whites saving them from slavery. My ancestors were abolitionists and fought in blue to free the slave, and yet their actions did not secure for their ancestors any love from the blacks to Whites, or thankfulness. I say that tongue-in-cheek of course, I don't, and I never have, expected any positivity from blacks simply because of the actions of my ancestry.
I am curious, however, what my thoughts on blacks would have been like if it weren't for big league sports being so popular and important growing up. I grew up thinking blacks were the best athletes and looked up to them, even envied them, for that because sports were the most important thing among boys. Had sports not been much of a thing, or if there were still separate leagues maybe that wouldn't have been a thing. I remember reading in Renegade Americans that jews used to be considered athletic, dominating boxing and basketball and then over time the image of them became nebbish. After reading Malcolm X's autobiography (it's actually a biography, not "auto" since Malcolm didn't write it) I think blacks are now viewed in the same way they were viewed in Malcolm's time, with suspicion, derision, and little trust in their capabilities. Malcolm regularly took advantage of the fact Whites couldn't believe he was intelligent and could outwit them.
