Is it true that you (a rationalist person, possibly american) would accept jealousy as an excuse for murder?

cousin_it wasn't moralizing one way or the other. He was suggesting game theoretic incentives not targets for righteous blame and shame.

Incidentally in some cultures such a policy would be appropriate. Particularly those in which:

• Genetic paternity tests are not available and customary.

Cuckoldry is a serious economic and social violation. Much like the other types of violation that people may need to challenge each other to duels over. Increasing the severity of the consequences of getting caught decreases the need for paranoid supervision.

Seriously, this reminds me of a group of 13 years old finding out whose penis is bigger to enrage those of shorter size. It is way too childish to pass unnoticed here.

This comment struck me out of place.
