The article doesn't give any reason why this would be the case, and it seemed a little stretched, anyone know why would farmers really want to kill hunters ?

ps: >Therefore, there can be no kings, no class of social parasites who grow fat on food seized from others.

This feels naive at best. Biology creates classes, strong, witty, devious, etc etc
