I don’t think he does. The whole point of Sauron trying to enslave Middle Earth is exactly the justification you need for the mass slaughter of the “enemy”. If the orcs were spending the days idly farming and smoking hobbit pipes, you would have a whole other argument against genocide.

Tolkien disagrees with you.
