Thomas cites himself (he absolutely loves to cite himself, he does it 19 times in 7 pages(!)), 'As I have previously explained, “substantive due process” is an oxymoron that “lacks any basis in the Constitution.”'

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.
