Banal

cf Hannah Arendt, "the banality of evil"

also Banal nationalism refers to everyday representations of a nation, which build a sense of shared national identity.[1][2] Examples include sports nationalism, the use of flags or national anthems in everyday contexts, and gastronationalism. The term is derived from English academic, Michael Billig's 1995 book of the same name and is intended to be understood critically. Billig's book has been described as 'the fourth most cited work on nationalism ever published'. https://en.wikipedia.org/wiki/Banal_nationalism
