You don’t make a scathing argument for a case you could never even get to be taken up by the other justices.
If we the people are saying to each other, “This is a dead-end issue because the Supreme Court will never do anything about it”, then so are the justices who know that Sotomayor and Kagan are blocking them from ever being able to do anything about it. Instead, Justice Thomas said that they are “evading” the issue.
IOW, you’ve got it straight from Justice Thomas. No mind-reading necessary.
