The Culture: Arch Points Out The Obvious

Arch embraces the inevitable.

This is him not only waking up and choosing violence, but deciding that Exterminatus is not the extreme option.

He has such a firm grasp on the psychology of Resentment that Chaos personifies that he is now ready to see the real-life counterpart.

That's right, this not something harmless. The end result of this in real world terms is the destruction of Civilization and the extinction of Designated Enemies.

You want to know the Death Cult and the Mammon Mob have to control the narrative down to the level of hobbyist pursuits? Because even the smallest of things can hold the power to expose them and thus give both form and name to an otherwise invisible enemy; if you can name it and shape it, you can kill it.

This is what those skilled in Sophistry know too well; that's why they play wordgame and deal in gaslighting as easy as breathing- and it's why they weaponize lore, history, and precendent--three forms of word-based foundation-building--in their attacks. ("It's just fiction", "It's just Your Truth", "It's just Oppressive Construcs" respectively, and when they seize power they waste no time changing it to suit, as Virginia recently showed again.)

GW didn't intend it, but via stealing Chaos from Moorcock to label their Cosmic Enemy they would provide a model for the very trans-national crime syndicate and death cult that threatens the world and all within it. The enemy noticed, and they cannot forgive or ignore this; by their reaction, you know that Arch's presentation is correct. This is textbook "Protest Too Much" revelation.
