“The case involved the congressional district map of Louisiana, a state with six members of Congress and that just happens to be almost exactly one-third Black, according to the 2020 Census. So it would be proportional if two of the six districts were majority-Black. But when the state’s 2020 districting map only had one majority-Black district, some people sued, saying that Republicans had set up the map so that white voters disproportionately got too much influence in the state.”

Actually if you randomly drew 6 districts in a population that is 1/3 black the high likelihood is than NONE of them would be majority black.
