It has a near mocking tone to it, especially the way he keeps referring to her by name. He effectively accuses her of discriminating against Asians, and seems to suggest in one of his hypotheticals that she would discriminate against - wait for it - a grandchild of Holocaust survivors.

Then there's this:
JUSTICE JACKSON then builds from her faulty premise to call for action, arguing that courts should defer to “experts” and allow institutions to discriminate on the basis of race.
Make no mistake: Her dissent is not a vanguard of the innocent and helpless. It is instead a call to empower privileged elites, who will “tell us [what] is required to level the playing field” among castes and classifications that they alone can divine.
Thomas, Toga-boy in good standing of the Bohemian Grove, is of course quite familiar with privileged elites.
