I thought the case for reparations was pretty good.

And it would help if the people commenting here read the linked article in the OP:
"Thanks to a compromise between Southern slaveholders who wanted enslaved blacks counted in the population, for the sake of boosting Southern congressional representation, and Northern whites who didnt, the framers enshrined the three-fifths clause in the Constitution. This agreement set the census value of a slave as 60 percent of the value of a free person. Even after the 13th Amendment neutralized the political (and moral) compromise by abolishing slavery, Jim Crow laws, which contravened the 14th Amendments guarantee of equality, stopped blacks from voting. The just answer today is to invert that ratio. If black Americans were once counted as three-fifths of a person, let each African American voter now count as five-thirds.
Reparations in America have come to mean free money, so any serious discussion about them also mandates a discussion of how much an exercise doomed to failure. Other ways of imagining reparations (as the spilled blood of more than half a million Union soldiers during the Civil War; as affirmative action in universities and workplaces; as subsidized education) dont involve cash payments, but they also dont do enough to combat the structural disadvantages black Americans face disadvantages that have gone largely unaddressed by our legislative and executive branches."
