By the time that same-sex marriage became legal nationally, public opinion on the subject had reached almost 60% approval levels according to polls by The Wall Street Journal, the Human Rights Campaign, and CNN, having been consistently over 50% since 2010 and trending consistently upward over the years prior.
Same-sex marriage, also known as gay marriage, is marriage between people of the same sex, either as a secular civil ceremony or in a religious setting. Same-sex unions are recorded in the history of a number of cultures, but marriage or similarly formalized same-sex unions were rare or nonexistent in other cultures. In the late 20th century, religious rites of marriage without legal recognition became increasingly common.
