I'm sorry, what?
So for one, your contention is that we have to the left over recent decades, to the benefit of black women and presumably other racial minority and/or lower socioeconomic cohorts - which would imply a general advancement of equality in society - and that is the wrong direction? Do you just not understand the implication there?
Beyond that, Said black woman is looking back at 1992 and seeing significant deterioration in reproductive rights/women's healthcare, erosion of the Voting Rights Act, multiple tax cuts for the ultra wealthy and corporations putting more of the tax burden on the working and middle class, and disinvestment in education - most of which disproportionately impact black people. So what am I missing that makes up for that and so much more to the point that the idea that the political environment has trended to the right is absurd?
Show your work here. Mainstream culture has gotten more liberal, sure. Divided but probably more liberal in aggregate. That's not matched in policy at all. The policy trendline and Overton Window have pretty clearly been moving right since Reagan was elected. Not necessarily a straight line but the overall direction.
