In the United States, it is no longer possible to pass laws banning the celebration of marriages between people of the same sex. This was established by the US Supreme Court on Friday 26 June in a ruling passed by five votes to four. Before the ruling, 37 states plus the District of Columbia already permitted same-sex marriage, but now no state can refuse to perform such marriages or decline to recognise those performed elsewhere.

The US administration greeted the ruling with an outpouring of joy, and United States President Barack Obama delivered a highly significant speech on the need to achieve equal rights for all minorities and forms of diversity, beginning with the right to marry. Moreover, as he has shown on more than one occasion that he knows how to do, on his Twitter account he launched the hashtag #LoveWins, which immediately became a global trend. Both organised and spontaneous demonstrations were held in many capitals and major cities. 28 June is, in fact, a symbolic date for the LGBT movement, and every year gay pride events are held around this date in various parts of the world. Berlin, Manila, New York, San Francisco, London. In Milan, around 100,000 people took part in Milano pride to "defeat prejudice and say yes to love". One particularly apt slogan was "Rights nourish the planet", paraphrasing the famous motto of Expo Milano 2015: "Feeding the planet. Energy for life".
