The latest battleground in America’s culture war over gender identity will take place Saturday on a volleyball court in Las Vegas.

The San Jose State University Spartans women’s volleyball team, which is at the center of a national debate over the inclusion of transgender women in women’s sports, advanced to its conference championship on Saturday without having played a single game in the tournament.

Twice during the regular season, the Boise State women’s volleyball team took a moral stand by forfeiting matches against San Jose State rather than competing against a player believed to be transgender.
