In 2020, evolutionary biologist Gad Saad published his The Parasitic Mind: How Infectious Ideas Are Killing Common Sense. He describes how in the postmodern Western world many ideas gradually arose that received a dogma-like status, that can only be criticized or renounced at the cost of being censured or even cancelled. In fact, Saad views these ideas presenting themselves as uncontradictable axiomatic principles as idea pathogens, comparable to how viruses and other parasites invade their hosts in order to take control of it and eventually destroy that host.
