Early last week, Jussie Smollett, the openly gay Black star of the Fox TV show Empire, was physically attacked while leaving a Chicago restaurant. The assailants reportedly put a rope around his neck, shouted slurs and threw a chemical substance at him, the Associated Press reports. No arrests have been made, though surveillance video has been released.

On Saturday, February 2, Smollett, who is also an R&B singer, appeared publicly for the first time since the attack. The occasion was his concert in West Hollywood. “The most important thing I can say is ‘Thank you so much, and I’m OK,’” he told the audience. (You can watch a video of the speech above.) The day before his concert, Smollett released a statement via Essence magazine, saying “During times of trauma, grief and pain, there is still a responsibility to lead with love. It’s all I know. And that can’t be kicked out of me.”

Since the attack, Smollett has received an outpouring of support from fans and activists alike—including members of the HIV community.

“Jussie is one of our country’s leading activists who has fought in the face of injustice and stood up for those disenfranchised because of the color of their skin or who they love,” said Raniyah Copeland, president and CEO of the Black AIDS Institute (BAI) in a statement. “We live in a climate where it is increasingly acceptable to partake in violent attacks on Black bodies and the LGBTQ community. We cannot ignore the toxic mixture of violence that specifically affects people at the intersection of these identities.”

According to the BAI statement, Smollett has been a volunteer at BAI since he was a teenager. He has served on the group’s board of directors and helped chair BAI’s annual gala.

Meanwhile, VOCAL-NY (Voices of Community Activists and Leaders New York), a health and justice group, organized a rally in Manhattan on Friday, February 1, to show solidarity with Smollett and to denounce violence against queer communities of color.

Jason Walker, the HIV/AIDS campaigns coordinator at VOCAL-NY, spoke about the rally and about violence against queer people of color, on The Brian Lehrer Show on WNYC, New York’s public radio station. You can listen to that here, and you can read more about the rally in this Gay City News article.

As the above tweet shows, Smollett has also helped promote HIV awareness through his role on Empire. He plays an openly gay character who is dating a man living with HIV. The storyline has brought issues such as pre-exposure prophylaxis (PrEP) and undetectable = untransmittable (U=U) to a large audience.
