Interestingly enough, "aporia" is what Deconstructionism uses to cause doubt in people through deconstructing meaning, especially between binaries (such as male/female). Feminism, veganism, Marxism, Black Lives Matter, etc., all use the Joker's tactics to mess with people's sense of established identity, and weaken them as a result. Aporia is being used with great effect on Western culture, and wreaking havoc on our cultural identity and sense of self.
