Respectfully, you may think you're developing a coherent argument, but you are jumping around between several unrelated points.

Does racism exist? Of course. It probably is even higher among rural and suburban individuals, on some kind of self-reported metric.

Does it have an appreciable, significantly negative impact on the lives of most non-white people in 2021? The evidence is pretty dubious on this point IMO, but of course it depends on your definition of impactful.

Is it related to gun violence? I don't see how.
