The American Psychological Association stated in 2004: "Denial of access to marriage to same-sex couples may especially harm people who also experience discrimination based on age, race, ethnicity, disability, gender and gender identity, religion, socioeconomic status and so on."
Asosiasi Psikologikal Amerika menyatakan pada 2004: "Penolakan terhadap akses perkawinan bagi pasangan sejenis dapat khususnya merugikan orang yang juga mengalami diskriminasi berdasarkan umur, ras, etnis, disabilitas, gender dan identitas gender, agama, status sosioekonomis, dan sebagainya."
