What does heterosexism primarily promote?

Heterosexism primarily promotes discrimination against non-heterosexual relationships. This term refers to the societal bias that assumes heterosexuality is the default or normal sexual orientation, often leading to the marginalization and devaluation of non-heterosexual identities and relationships. This framework can manifest through various means such as exclusion, prejudice, and the invalidation of the experiences of LGBTQ+ individuals. The impact of heterosexism can be seen in policies, social attitudes, and even microaggressions that affect those who do not identify as heterosexual.

In contrast, the other options focus on acceptance, advocacy, and equal rights, which stand in opposition to the discriminatory nature of heterosexism. Acceptance of diverse sexual orientations fosters inclusivity, equal rights across genders supports fairness and justice for all sexual and gender identities, and support for LGBTQ+ advocacy actively works against the discrimination that heterosexism promotes.
