Picking out the relevant parts of Hellified's post:
youre use of the martin/zimmerman incident as an example shows that you have no idea what the issue was to black people.
On the contrary, I think most white people have been inundated with the matter of what Black People Think About the World. I don't deny that some people can shut it out, like the people you mention who have no problem with reporting black people for the Crime of Being Black. But it's one thing to say "Black People Think X," and another thing to say, "Black People are Correct About Everything." In the case of Zimmerman, I wouldn't have minded seeing him do some jail-time for manslaughter. But a lot of people, not exclusively blacks, wanted to treat Zimmerman's act as murder in the first degree, which it clearly was not. Why did the District Attorney overcharge Zimmerman? I can't think of any reason except to mollify the extremists by subscribing to their narrative-- and so Zimmerman did no time, because it was important to the extremists' narrative to call him a murderer.
show where blacks as a group have established laws in this country that discriminate against anyone
Are you going back in history now? There were some official laws on the books, like laws against racial intermarriage, but by and large most of the strategies used to oppress black people were not laws, but customs. There was no law on the books that said, "Whites ought to lynch blacks every once in a while to keep them in line." It was a custom, however repugnant, that white people evolved "off the books." While you can argue that the lynched man doesn't care whether he was killed by law or by custom, it makes a difference to us now, or at least to anyone answering the oversimple claim that racism is systemic. On the contrary, the law's claim to be rational and non-partisan is the black American's only weapon against the chauvinism of custom.
On a related topic, I put it to everyone here: have you ever seen a black person prosecuted for having simply been in the presence of a white child? I've seen a lot of false crimes attributed to black people over the years, not least being the sin of being in the company of adult white women. But this idea from "black-ish," picturing black men as pedophiles, is an idea I don't really think is widespread, and I suspect the show's writers made it up out of whole cloth. However, if anyone has a specific example of a pedophile prosecution, feel free to roll it out.
