I don't think anyone who performs it realizes what they're retweeting. There is no idea how imperialist (because derived from Hegel) the decolonial concept is. The British used precisely cultural difference and incommensurability to dominate Africa and India.
It is precisely this culturalism and its implicit imperialist lineage that is the bitter irony of its having been forced on first peoples via theory class, as the currently correct form of righteous and ultimately ecocidal religion.
One rather tries to flush that legacy down the toilet.
