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.

The one enemy that appears briefly before getting beaten up into oblivion?

I agree that a lot of dark stuff happens in Jojo (heck, the protagonist of the 5th saga is a mafia boss), maybe it’s best for mature audiences.

I think the orcs/demons being hell-bent on killing humans is a sufficiently good reason.

It’s not that short, you just need to pick a genre different from shounen if you don’t like fanservice. Also many older shounen are good, think about the Digimon, Pokémon and Gundam franchises to name a few famous ones.

Didn’t Google Stadia do the cloud thing and failed miserably?
