On this day in 1954, the Supreme Court handed down Brown v Board of Education of Topeka, Kansas, which ended "separate but equal" education after finding that the two concepts are antagonistic. Also on this day in 1954, the City of Chicago announced plans for the Stateway Gardens housing project, which eventually replaced an African-American slum with a high-rise hell-on-earth housing African Americans. As historian John R. Schmidt comments, "Maybe the new public housing projects were an attempt to keep Black people on 'their side of the tracks.'" (They were; he's being sarcastic.)
A similar pattern exists today. Despite historic, unprecedented support for the LGBT community throughout most of the U.S., the right has taken on the non-existent issue of predators in bathrooms to win votes in an election year. The small minority of people who (a) care about this issue and (b) are afraid of gays nevertheless has support from latter-day Sheriff Clark figures like Texas Lt. Gov. Dan Patrick and other Republicans.
Progress is never smooth. I just wish people on the wrong side of history would get out of the way sometimes.
