Thomas literally wrote in concurrence that this decision also implies that Lawrence, Obergefell, and Griswold are on the chopping block next.
He then goes on to say outright that Griswold, Lawrence and Obergefell should be reconsidered. I take that to mean the majority reactionary court, who also do not believe in substantive due process, will overturn those. And it also implies a call to action for reactionaries to start building cases.
