And that leaves only one logical choice to replace him.
"Asking Hannah Gadsby to host the Oscars is the most obvious thing in the world, come the eff on, Academy", wrote Rachel Vorona Cote on Twitter.
The last Australian to host the Oscars was Hugh Jackman in 2009.
"That's a hard topic for me because I'm a big fan of Kevin Hart and I know that he probably didn't mean any malice by it but I mean I think an apology is due if it hasn't been given before", Rodriguez said on the red carpet for the GQ Man of the Year awards Thursday night.
The gay media watchdog group GLAAD said it has reached out to Oscars broadcaster ABC, the Academy of Motion Pictures Arts and Sciences and Hart's management to "discuss Kevin's anti-LGBTQ rhetoric and record".
"The reason why I passed is because I've addressed this several times", he said. But they had already been screen-captured and been shared online. I have nothing against gay people, be happy.
In an earlier post on Thursday, Hart wrote on Instagram that critics should "stop being negative" about his earlier anti-gay remarks.
"I'm nearly 40 years old". In an accompanying video, a shirtless Hart said he wasn't going to "let the craziness frustrate me".
At a Hollywood event Thursday night, comedian Kathy Griffin, whose career suffered previous year when she posted a photo on social media that looked like a beheaded President Donald Trump, said Hart messed up, yet had empathy for the situation.
Hart's attitudes about homosexuality were also a well-known part of his stand-up act. That's a fear. Keep in mind, I'm not homophobic.
Terry Crews, who described Hart as a "brother", said he respected Hart's decision to walk away from the show.
