Cisnormativity. All systems and attitudes in society that make being cisgender the dominant norm. These can go as far as to push the false idea that trans and nonbinary people don’t exist. It’s one of the roots of social rules that ridicule or punish people for behaving in a way that doesn’t match the gender they were assigned at birth.

Synonyms:
cisnormie, cisnormies, cisnorm, cisnorms
