NEW YORK: Hundreds of thousands of people from New York to San Francisco marched on Sunday to celebrate gay pride, honor those killed in the Florida gay nightclub massacre, and promote tolerance. Democratic presidential candidate Hillary Clinton, buoyed by a double-digit poll lead over Republican Donald Trump in the race for the White House, joined the tail end of the parade in New York. In San Francisco, the crowd cheered and electronic music blared from floats, a group carried placards with photos of the Florida victims, and men in leather bondage walked the route under bright sunshine. “LGBT Americans still face too many barriers. Let’s keep marching until they don’t,” tweeted Clinton, joining a slew of elected state and city Democrats who took part in the march exactly a year after the US Supreme Court legalized gay marriage across the country. New York, which prides itself on being one of the most diverse cities on the planet, is the birthplace of the US gay rights movement.
