The WNBA's divided reaction to the trans debate has deepened after Seattle Storm star Stefanie Dolson took a bold swipe at rival Sophie Cunningham.

Indiana Fever superstar Cunningham drew intense scrutiny recently when she spoke out about 'protecting' girls from playing against biological men, and the fallout continued at pace in the notoriously woke northwest city on Tuesday night.

Arriving for the Fever-Storm game at Climate Pledge Arena, Dolson appeared to make a very pointed statement to Cunningham by wearing a t-shirt which read 'trans rights are human rights'.

Photographs of the political statement were posted by the team's official accounts on both X and Instagram, sparking a vocal reaction from both sides of the debate.

While many praised the Storm, and Dolson, for speaking out, others slammed the shirt, with one writing: 'Gross.'

Another added: 'Then you should have no problems playing against biological men.'

Before the WNBA game on Tuesday night, anti-trans protestors also held a rally outside the arena in support of Cunningham, whose comments are continuing to make headlines around the world.

The group held up signs which read 'Thank you Sophie' and 'Protect Female Sports', chanting in support of Cunningham and her now-viral comments.

Inside the arena, meanwhile, the division continued with both pro and anti-Cunningham signs seen on the ESPN broadcast.

While one fan held up a 'no hate in these United States' rainbow banner, another fan's sign read: 'Thank you Sophie for speaking up for girls'. 

Reports from outside the arena claimed arguments took place between pro and anti-trans protestors, but it is understood there was no physical violence.  

Cunningham initially sparked the widespread reaction when she underlined her support for the movement aiming to protect women's sports while talking with ESPN, before later doubling down on Instagram. 

In her initials comments, she said: 'I got a lot of negative feedback about me hating trans. And I'm like, "I never once said that". 

'I think that I am here to extend love. But I also think with that love is truth, being honest. And I want to protect young girls in a locker room, or young girls in sport who shouldn't have to go against biological men.'
