The turn from your initial comment to this was about as abrupt as Hulk Hogan's in 1996.
Your experience is sadly very parochial, and simply anecdata.
Meaningful systemic racism is far more problematic than your experience with a few rural black males.
And yet we are so quick to dismiss their own livd experience and/or not believe them. Frankly "this happens almost never, but it happened once to me" is far more real to pretty much every human on this planet. I was routinely beat up by a certain racial group of people growing up. I still cannot feel threatened by their presence, from what I know of the brain it's literally encoded in my body.
Your experience is valid, and the emotional response probably serves a survival goal, but it still is not data.
