Oh, they know, they're part of the destabilizing.
Grind is obviously a shill. He's so overt, he practically treads on being honest about it. He's so earnestly stupid, he might be an American (trailer park variety) after all.
In addition to the other bots, the lower rungs and filler drones are just the loser reject crowd, uneducated dead enders from broken homes with lackluster lives, a reeking heap of self hatred, and too much time. Destroying the America that bypassed them so they can seek a renewal in its ashes is what they crave. Isn't that what the low browed marginalized dysfunctional haters always do? Wrecking what they can't be a part of?
These are the disposable brownshirts. Destabilization is the only thing they're good at and like in Hitler's Germany, their only value.
