Heteronormativity is a social and cultural concept that assumes heterosexual relationships are the default or "normal" way of being. It often leads to the belief that people should be attracted to the opposite sex and that traditional gender roles are the standard. This perspective can marginalize those who identify as LGBTQ+ or who do not conform to these norms. The implications of heteronormativity can be seen in various aspects of society, including media, education, and law. It can create environments where non-heterosexual identities are overlooked or discriminated against, affecting individuals' rights, representation, and mental health.
