I don't understand your comment
But in a nutshell, personal anecdotes aren't always reality.
Media of all kinds, over the years, have certainly contributed to the narrative to fear black people. Reifer Madness comes to mind as one example. And there are dozens of others. This institutional racism has slowly eroded, but it's still there.
This is reality, even if you can't see it, don't want to admit, or weren't personally taught by your parents to fear black people. This is more societal, more subconscious.
Listen, I don't disagree entirely. The below will probably make you uncomfortable, but it really shouldn't because it's all true.
I don't recall being taught to fear/hate black people. But I was raised in an environment with almost no black people (very early on) before being among quite a lot of black people as I grew up. So I buy into the idea that difference and apprehension can be deeply engrained, even if there was never a racially charged statement made in my house. Anecdotally, I got ambushed once after a game (by black guys I didn't know), and the guys who sought retribution for over it? Black buddies. So I'm sure I had a pretty complicated mix of fear/friend in my system.
But this seems like another scenario where it's all or nothing, where there is no room to discuss actual truths and nuances of those truths, because they make us all feel uncomfortable. The uncomfortable part for me is that my parents and my lovely hometown probably did reinforce some prejudices and biases, even though it wasn't their intent. There were good and not great parts of town based on race. Restaurants for them restaurants for us. Sports, however, broke down a lot of that separation.
The uncomfortable part for those saying "it's all systemic racism" is that in my area pretty much all of the non-family violent crime, and a huge majority of the property crime, is committed by black people. And not all black people, it's almost all from 15-35 year old black men. That's in a city run by black folks, policed by black folks, and home to the world's largest black middle class. It's usually directed toward other black men, sadly. But to white folks too.
So, is it the product of prejudice/bias to get wary when a car full of 18-35 black guys pulls up on your street? Yes. Is it the product of societal-influenced fears? Maybe, but not exclusively. We love to discuss the lived experience of people, unless they're white, in which case their lived experience is to be ignored. If you want to talk about power structures and critical race theory, maybe we should tell white people their experiences should take a backseat and aren't important. But otherwise it makes no sense, and I don't think having half the conversation is very useful. FWIW this isn't a "what about white people thing." I have no interest in being heard about white grievances right now (nor do I really consider white people some cohesive group), but I do have an interest in talking about where biases arise from and contradictory positions society takes on these topics.
