It is true that absolute relativism cannot pass judgment on others passing judgment. So what reasons might someone have to use relativism to respond to someone passing judgment? It has been brought up on this blog that persistent disagreement is evidence of irrationality, so the relativist might be explaining why they themselves decline to pass judgment in a similar manner on the issue being discussed. They might also personally disapprove of just what the judger is decrying, but also feel compelled to remind everyone that their opinions are just that: opinions.
This idea is intriguing, but I don’t know if it would be as popular as the other lottery. It can be hard to maintain excitement about something for a long period of time (with the regular lotto you can recharge between when you find out you’ve lost and when you buy your next ticket).
