Naomi Osaka has been showing support for George Floyd, an unarmed Black man who died last month after a now-fired Minneapolis police officer pressed his knee into his neck.

“I see people been ghost on twitter for a week when the events first started unfolding, but as soon as the looting started they sure are quick to give us hourly updates on how they’re feeling once again,” wrote Osaka in another tweet.

She then accused some of staying quiet about the call for racial justice, outside of posting a black square on social media for Blackout Tuesday, a day where people and organizations protested on Instagram.

“I’m torn between roasting people for only posting the black square this entire week…Or, accepting that they could’ve posted nothing at all so I should deal with this bare minimum bread crumb they have given,” Osaka tweeted June 2.

In one of Osaka’s responses to her critics, the two-time Grand Slam champion said it’s ridiculous for people to expect her stay silent on Black issues just because she’s a professional athlete.
