She should have thought this through!

Roseanne has been abruptly canceled despite great ratings, after Barr sent a racist tweet that caused a huge backlash almost immediately.

The comedienne posted a photo of former President Barack Obama's aide Valerie Jarrett, and made derogatory remarks with her accompanying sentiment. "Muslim Brotherhood + Planet of the Apes + vj," she wrote, before adding that Muslims were "not a race."

Barr deleted the tweet and issued an apology, but it was too late.

“I apologize to Valerie Jarrett and to all Americans. I am truly sorry for making a bad joke about her politics and her looks. I should have known better. Forgive me-my joke was in bad taste," she shared.

Show writer Wanda Sykes was the first to jump ship, and actress Sara Gilbert expressed her outrage and tried to distance herself from the show. "“I will not be returning to@RoseanneOnABC,” Sykes tweeted.

"Roseanne’s recent comments about Valerie Jarrett, and so much more, are abhorrent and do not reflect the beliefs of our cast and crew or anyone associated with our show. I am disappointed in her actions to say the least. This is incredibly sad and difficult for all of us, as we’ve created a show that we believe in, are proud of, and that audiences love— one that is separate and apart from the opinions and words of one cast member," Gilbert explained on social media.

Ignorance has real life consequences!
