Ry Shissler, a 40-year old cartographer who swims the backstroke, was planning to compete internationally for the first time during the WorldPride celebrations that start this month in Washington, D.C.

But the trans athlete and their team, Toronto’s Purple Fins, made the difficult decision to skip the games and the Pride events in the U.S. entirely, worried about their treatment at the border and beyond.

A self-described “gender free” swim club, the Purple Fins is one of several aquatics teams with bi, non-binary or transgender athletes whose members told Reuters they are not comfortable visiting the United States right now.

“Are my rights gonna be respected? Can my teams’ rights be respected? Are we going to be assaulted and have the authorities defend us, instead of the attacker? Those are all questions we couldn’t definitively say yes to,” said Shissler, who identifies as a “trans person of unspecified gender.”
