There is a lot to unpack here and, being honest, some of it im just not willing to discuss. Mostly because I feel it has been discussed at length, at this point, and I shouldn't bear the burden of educating white people on these things.
You say you asked for more evidence and only received my mocking you but I would rebut why didn't you do the work to find out more? You see, when I read about the initial story and saw the video, I thought, wow that's messed up, I can believe it, and my curiosity lead me to look into the issue because I'm invested in the cause of racial inequality. It means something to me. In that, yes, there was more evidence being provided (more on this phenomenon later.)
That's what I mean about "what is your default posture?" If you are operating from the position "systemic racism exists" and "systemic racism is a problem" and "we need to fix systemic racism" then when you hear about a case of just that and see a video alleging that, if you care, if you are invested, you would go seeking information, you move into action. A privileged person waits to be provided more. To illustrate: your daughter comes home and says, "Dad, I've been assaulted by Joe the mailman." You ask what happened? I doubt your response to her recount would be, "Hmm, that doesn't sound like assault. Joe isn't that guy. Do you have more examples to provide?" No, your default response would be to believe your daughter and, from there, you move into action. That isntvto say if you found out she was mistaken or wrong you wouldn't acknowledge it. But, at first? Yeah, you are going to get to the bottom of it, operating from the stance "it happened."
Why? Because it's your daughter. You care. You are invested. Until persons like yourself are empathetic enough to have that level of concern and investment, nothing will change. It shouldn't take me to give you more. As for the other stuff, that all involves privilege and that's a topic where either you understand or you don't. If you, as a white man, don't understand your level of privilege, it's not worth my time discussing it. I, as an able-bodied black man, clearly understands the privileges I have. One, as a man. I get to walk in a way in this world women can't. Yes, Oprah, singularly, lives a way more lavish lifestyle than I could ever dream of, but that doesn't diminish the privileges I get, even over her, as a man. The same goes for being able-bodied.
You trying to draw an equivalence between our experiences of racism and discrimination to say you are versed enough to "spot" racism is, frankly, comical. You couldn't even be bothered enough to do more research on this issue which is a pretty big tell that you aren't experiencing this type of discrimination on a level where it's impactful on your life or your family's. Questioning whether I can "see it," furthermore, let's me know you just aren't "there" yet. You are more invested in protecting someone being accused of being racist than protecting those claiming to be victims of it.
In other words, Joe's reputation is more important to you than your daughter's accusation. Thanks "friend," but no thanks.
Oh, I almost forgot. My parenthetical point. Much like one rape victim coming forward provides the courage, cover, support and willingness for other victims to come forward, had you dug deeper into this story, you would have realized that once this story broke, other minority parents started providing more verbal and video credence to this matter. For some, it happened, and they were too embarrassed to make a stink over it, treated it as a one-off and moved on, perhaps didn't notice or even gave the benefit of the doubt. Which is why your default posture and believing us is important. Sure, one accusation of rape stands alone, but ten accusations is harder to dismiss. But, your posture towards #1 greatly influences what comes next. "Believe all women" doesn't mean every woman gets carte blanche to make any accusation without scrutiny and is automatically believed, the accused punished with no due process. But, our posture to initially believe a woman claiming assault is a societal acknowledgement that we recognize that type of crime is 1-prevalent, 2-disproportionate to one demographic, 3-under reported by that demographic, and 4-needs overwhelming support to combat its prevalence.
Your default position needs to change. My gut says when you become the victims, disproportionately, of it you will. All I'm asking is that you keep that same energy if you get treated like you so willingly are to allow us to be treated.
