"The Cosby thing I took seriously because I know one of the victims, who is not going to come forward," he tells the
magazine. "I had a personal connection to it, where somebody that I care about said that's exactly how it went down."
"Obviously you have to make sure things are true," he adds. "Everything everyone says isn't true. But if you don't believe women or take their accusations very, very seriously, women will not speak up. And if women don't speak up more women will be raped."
Cosby has been accused by more than two dozen women of sexual misconduct in allegations that span several decades, though the comedian has maintained his innocence and has never been criminally charged. However, Cosby did admit to giving a former Temple University employee three half-pills of Benadryl while testifying under oath during a 2005 deposition. The sexual-assault suit was settled on undisclosed terms in 2006. He also admitted, in more generic terms, to having obtained sedatives to give to women in the past.
"It's much easier not to believe the accuser," Apatow says. "With Cosby, for a while people were thinking, 'They're all gold diggers.' And at some point enough women came forward that the world knows this happened and that he is clearly some sort of sociopath."
Just last week, Apatow called out Whoopi Goldberg for her comments on the ABC show defending Cosby. ET caught up with him at the Trainwreck premiere in New York City on Tuesday, where he explained his outspoken stance.
"Well I think everyone in the world's gonna slowly see that sadly, he did a lot of terrible things," he told ET's Kevin Frazier. "I think people are very slow to want to believe it because he's someone we all loved for so long. But he did terrible things."
"I think women need us to believe or they won't come forward and say what happened to them," he added. "So it's not just about Cosby. It's generally about the atmosphere of why do we not believe women when this happens to them?"
Though it's worth nothing that Whoopi has since changed her mind about the situation. During Tuesday's episode of The View, she commented, "It looks bad, Billl. Either speak up, or shut up, because people know now there's a lot more out there than they thought."
