I'm sure the author's intent is to portray Redcloak as being in the wrong here, but he's really not. Here's the deal that was brought to him:

"Yeah you and your race were created by the gods as nameless NPCs for clerics to slaughter and level up. You were given the shitty barren parts of the world with no good ore or farmland because your purpose as food does not require you to have more. Now this ruckus you're making about it? That's not gonna fly. You stop it right now and accept your lot in the world or the entire world is getting blown up. And if you bend the knee to our ultimatum, we'll reward you with maybe some trade deals that will certainly be reneged on or letting you hold some land that you certainly won't be allowed to keep once the immediate danger to the Gods is over."

Wouldn't you give the proverbial finger to this too? Wouldn't this insulting attempt at diplomacy require a response of "I'd rather see it all blow up then" by any rational being with even the slightest sense of pride?
