Are you suggesting that racism is a predominantly urban phenomenon?
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.
