Zmirak is setting up the argument that anyone who believes in any kind of absolute morality is disqualified from the USSC.
The reason that is ridiculous is that the Constitution is written for a people who subscribe to a set of absolute moral laws.
Losing that belief has already made the Constitution a blank slate for leftist activist judges.
The argument is that the only absolute is that there are no absolutes—all morality is relative and subjective, viewed through the “culture” of the aggrieved demographic.
