Comedian Roseanne Barr believes people who choose to eat at Chick-Fil-A deserve cancer.

The 59-year-old Barr, who is best known for starring in the ABC situation comedy Roseanne, took to Twitter on Wednesday to express herself as Chick-Fil-A customers lined up at the eateries in a show of support for CEO Dan Cathy.

“anyone who eats S--- Fil-A deserves to get the cancer that is sure to come from eating antibiotic filled tortured chickens 4Christ,” she messaged to her nearly 130,000 followers.

She later added: “christian liars: I never wished cancer on you at all – jesus will punish u 4 ur deceit – I said processed foods cause cancer - #chickfilA.”

Cathy created a firestorm of protest when he said that gay marriage is “inviting God's judgment on our nation.” Wednesday was organized as a day of solidarity with the fast-food chain's outspoken executive.
