Political scientist Emily Gill draws an extended comparison between religious belief and sexuality, both central components of one’s personal identity. Using the religion clause of the First Amendment as a foundation, Gill contends that, just as US law and policy ensure that citizens may express religious beliefs as they see fit, it should also ensure that citizens may marry as they see fit. Civil marriage, according to Gill, is a public institution, and the exclusion of some couples from a state institution is a public expression of civic inequality.
