I look at it another way which is far scarier.
In parts of the country where black people are more religious and hardworking the numbers that dislike whites are probably much lower, closer to 10-20 percent. Which means many areas, guessing here, like Philadelphia, Louisville Ky, St Louis, Memphis, NYC., Atlanta etc. They are MUCH higher than the rates the poll suggested.
I’d bet there are large areas in those Dem ran Urban cities where virtually or nearly ALL black people hate whites. (assuming the poll is true and close to representative)
