Definition - What does Same-Sex Marriage mean?
Same-sex marriage is a marriage that is between people of the same gender. In the U.S., the legal right to allow a same-sex marriage was validated in June 2015. Since then, there have been reported cases of a few county registrars who refused to perform marriage ceremonies between people of the same sex, but in all cases, they were legally forced to perform the marriage ceremony regardless of their personal objections.

The ban on same sex-marriage was refuted by many in the U.S.; subsequently, a landmark court case, Obergefell v. Hodges, went to the Supreme Court. The Supreme Court determined that the ban was unconstitutional.
