Adolf Hitler really got it wrong, metaphorically, when he called Jews a fungus and proposed that humans (Aryan humans) could easily remove them all from Europe and thus restore it permanently to its former state of racial purity.
True, the fungus will starve unless they are successful in dissolving the physical (and mental) bonds we use to try to keep 'pure' concepts like wet fluids and dry solids from co-mingling in a slime like fashion on top of a piece of damp wood.
The fungus are thus a highly appropriate metaphor for the intermingling hybridity that Hitler (and Modernity) so hated.
