There are a few here, and many elsewhere, who are just fine believing all sorts of outlandish conspiracies that carry with them not a shred of evidence to support the claim. One example is a stolen election in 2020, but there are ideas far less feasible and far crazier than that one. Evidence needed? Not really -- Trump said it, Alex Jones said it, Rudy said it, Rush said it, Sean or Tucker or Laura said it.... that's good enough.
But when a black person shares their experiences, or when a group of black Americans express the reality of common experiences, there is, from the very people who buy the evidence-lacking conspiracies, a tone of resistance, reluctance, and denial. You're not buying it, you're searching your brain for "what abouts" and double standards to counter the claims. If one's knee-jerk response (first thought) is to question the observations of a black person, it's evidence of prejudice, or bias, or racism.
Of course it's OK for logical criticism of a person's comments (as in the case of Lebron) when the person's own logic falters. But notice that almost everyone here who criticized Lebron also acknowledged in some way their acceptance that there is a difference in how blacks and whites are treated in America IN GENERAL (certainly not always). And while there are some socio-economic and behavioral explanations for some of the treatment of blacks in some circumstances, there is acknowledgement by most that at least part of the difference (again, in general) occurs because of skin color. While I realize it's frustrating for some that there is so much focus on race whenever a black person is involved in an incident, I think we need to continue to get better at our awareness of, and management of, the role race plays in our subconscious and our conscious actions. I know this is something I try to get better at and am not all the way there for sure. America is not striving for a more perfect union unless we continue to get better at dealing with this.
