In late May, a transgender woman named Vivian was viciously attacked while walking on Hollywood Boulevard, a reminder of the sharp-edged danger still facing the transgender community. "As much progress as there has been, we have to live with one eye open, always looking over our shoulders," Rodrigo Lehtinen, 27, said Saturday afternoon as he stood in a courtyard a few blocks from the near-fatal beating. Lehtinen surveyed the scene before him: a lively group of about 400 transgender men and women gathered for the 14th annual Trans Pride L.A. festival. "There are still terrible reminders of the problems we face, like the attack on Vivian," he said. "There are also more moments like this, where we can come together, openly, without living in fear."
