Where are you getting crime statistics that detail motivation?
I have also lived in the south (in fact have spawned from it), and I've lived in one of the wealthiest towns in the country, and also, after my marriage and in my travels, in some of the poorest, so I know about the gunshots, I know about the crime, I haven't always escaped unscathed or with all of my possessions.

And yes, I know that people of other races are capable of being bigoted and racist. Of course they are. I'm also not denying that interracial violence exists or that places with large minority populations also tend to have greater crime rates. I'm saying that that is symptomatic of larger issues and a cycle where we have to make some changes to the system to expect changes in those conditions, that these are issues of correlation and not causation.
Racism is complicated, and far more complicated than you appear to think. The only way of measuring it isn't by deaths and crime. And of course it is impossible to gleam the motivations and to what extent the perpetrator's views on race played into these crimes from those numbers alone.
The reason it's presented to you so often as a white problem is because they are the ones at the driver's seat. They are largely the ones in opportune positions. Racism doesn't have to be malicious, it doesn't have to be overt. It does have to affect our perceptions and the opportunities (did you watch the video, by the way?) that others are presented with. And when even some of the people with the power in this country hold overtly racist views--which many do--or when around half (I suspect you won't agree to consider "most," or "almost all," which I would find much more appropriate) of the people with the power have some degree of racial bias that they may or may not be aware of that affects how they treat people of a minority race, it becomes a problem of those people, and the problem we have to highlight and address.
