Amid a sea of rainbow flags and sequined costumes, hundreds of thousands joined Pride in London, showing their support for transgender people in the wake of a recent UK court ruling. For many, the event was both a celebration and a protest. “My human rights should not be up for debate,” said Chase, a 23-year-old transgender man. Others, like first-time attendee Dominic, said the scale of the turnout showed growing solidarity: “It kind of shows the amount of support we’re getting right now.” Like thousands of others in the United Kingdom, Chase will no longer be allowed to use certain single-sex spaces -- men's toilets and changing rooms in this case -- following the publication of new guidelines by the UK's equality regulator (EHRC) at the end of April.
