Carano was dropped from the Star Wars spin-off series this week after she shared an image on her Instagram Stories which compared the treatment of Republicans in the US to Jewish people in Nazi Germany.
A petition on charge.org, entitled 'Keep Gina Carano in The Mandalorian', reads: "This is a counter petition to support Gina Carano for keeping her role in The Mandalorian.
"Everyone is entitled to an opinion whether it be right or wrong.
"Your political views, as well as your social media walls should not dictate whether you do your job well or not.
"SJWs [social justice warriors] should also not have the power to remove someone from a work place just because they don't like your opinion/view.
The former MMA star was let go from the show after she shared a post that read: "Jews were beaten in the streets, not by Nazi soldiers but by their neighbours... even by children.
"Because history is edited, most people today don't realise that to get to the point where Nazi soldiers could easily round up thousands of Jews, the government first made their own neighbours hate them simply for being Jews.
"How is that any different from hating someone for their political views?"
Following the post, the hashtag #FireGinaCarano began trending across social media with many calling on Lucasfilm and Disney to ditch the star for her remarks.
In a statement, a Lucasfilm spokesperson said: "Gina Carano is not currently employed by Lucasfilm and there are no plans for her to be in the future.
"Nevertheless, her social media posts denigrating people based on their cultural and religious identities are abhorrent and unacceptable."
Carano, 39, has said she's since signed a new deal with the right-wing media outlet The Daily Wire and has said she wants to send a 'message of hope' to anyone 'living in fear of cancellation'.
Speaking to Deadline, Carano said: "The Daily Wire is helping make one of my dreams - to develop and produce my own film - come true.
"I cried out and my prayer was answered. I am sending out a direct message of hope to everyone living in fear of cancellation by the totalitarian mob.
"I have only just begun using my voice, which is now freer than ever before, and I hope it inspires others to do the same."
She added: "They can't cancel us if we don't let them."
