Almost twenty years have passed since that famous anti-bullying ad, but Duff is talking about it again. In a recent interview, she got a little choked up looking back at the message behind the PSA. The issues it tackled? That’s still here. And it’s still personal. Duff remembered why the campaign mattered back then, how much it meant to her young fans, and why fighting against bullying and hateful language is just as important today as it was then.

Hilary Duff on her ‘Think Before You Speak’ campaign

Duff recently sat down with Gay Times and talked through the whole experience of her doing the ‘Think Before You Speak’ campaign. Back in 2008, she filmed the PSA as part of the campaign, teaming up with GLSEN (the Gay, Lesbian, and Straight Education Network). At that time, “that’s so gay” was everywhere, as teenagers said it all the time without thinking about how hurtful it really was.Duff explained how she got involved: basically, someone asked if she cared about the issue and wanted to be part of the project. Duff responded, “I think I was just asked if I was interested in being in the PSA and if I cared about the topic at hand and, of course, I did.”Duff remembered how many kids would come up to her to say thanks — they told her they finally felt seen and supported. “I think they felt represented and stood up for and at that time, and in this time, it’s really important to feel safe and feel seen,” Duff recalled.Sf for the PSA itself, it was simple but powerful. In the ad, Duff overhears two women in a store, and one of them calls a top “so gay.” Duff steps in, calls it out, and she tells them not to use “gay” as an insult because it’s just not okay. The video closes with her voice: “When you say ‘that’s so gay,’ do you realize what you say? Knock it off.” The whole point was to show how everyday words can hurt, and to get people to think before they speak.The campaign was a big deal. It even won a Gold Bell award and, years later, still goes viral on TikTok. People have spoofed it, sure, but Duff knows it still means a lot. “It’s still the right message,” she said.While talking about all this, Duff got visibly upset. The topic makes her really angry and sad, too. She even apologized for tearing up. “It’s 2026, and who cares how anybody wants to be? Nobody’s bothering you. I just wish people would let everyone be who they want, be happy, be loved.” It’s that simple for her.Duff revealed that what really gets to her is that people still judge and hate others for being themselves, for their identity, for the color of their skin, and for their choices. “It bums me out,” she said. “It makes me so sad.”The ‘So Yesterday’ singer is also frustrated that prejudice keeps hanging on. If she had to write the PSA now, Duff admitted she’d need to think about it, as she’s got a lot of anger about the whole thing, but she knows, “that’s not the way to spread a message, either.”Who is Hilary Duff?For the unversed, Hilary Duff first shot to fame as Lizzie McGuire on Disney Channel, making her a huge name in the early 2000s. She has since had a successful run as both an actress and a pop singer, plus she’s always been involved in charitable causes like youth programs, disaster relief, anti-bullying efforts, and more. And that “Think Before You Speak” PSA? It still stands out as one of the most memorable moments in her activism.
