The event comes in response to criticism faced by WNBA player Sophie Cunningham after she stated that biological men should not compete in women's sports or share women's locker rooms.
Cunningham plays for the Indiana Fever, and the team will tipoff tonight against the Dallas Wings.
Mary Elizabeth Castle, a director at Texas Values, says the Dallas event — which Texas Values helped organize — is part of a growing nationwide movement led by figures like Riley Gaines and athletic apparel-maker Jennifer Sey.
Addressing concerns that arena staff might restrict certain apparel featuring chromosome designs or slogans, Castle points to what she calls a double standard in pro sports marketing.
"You had a WNBA coach wear a Trans Kids Matter shirt, and then you also have WNBA-made Pride t-shirts for Pride Month with different pride messages. So, if they're able to do that message, surely we can have our biological reality shirts, but we're really confident they won't pull that on us," Castle states.
She adds that organizers are prepared to defend attendees' free speech rights at the arena, noting that high-profile state officials will be on hand for the game.
"At Texas Values, we have our First Amendment talking points ready, and Texas Attorney General Ken Paxton will be at the game as well. So, it'll be hard for them to try that against us," Castle says.
Organizers are advising attendees to arrive early by 3:30 p.m., bring water for the heat and wear visible supporting clothing.
Castle says she hopes grassroots groups in other cities will follow suit as the WNBA season continues.
"So, if you're interested in following Sophie's games, just look at her schedule. I encourage you to plan that rally. I encourage you to continue to follow Sophie at all of her games and support her," Castle says.
Organizers say merchandise and posters will be provided to volunteers on-site before the doors open for the game.
