Grant Gustin, who plays Sebastian Smythe, an openly gay member of the Dalton Academy Warblers on the Fox musical-comedy Glee, has quit Chick-Fil-A.

The 22-year-old Gustin on Tuesday responded to the firestorm of controversy created by Chick-Fil-A President Dan Cathy's recent comments opposing gay marriage. Cathy unleashed a firestorm of controversy when he said gay marriage is “inviting God's judgment on our nation.” In a subsequent interview, Cathy insisted the company doesn't harbor an “anti-gay or anti-anything policy or attitude toward anybody that's out there.” Between 2003 and 2010, Chick-Fil-A gave nearly $5 million to groups opposed to gay rights, according to Equality Matters.

“I'm officially done with Chick-Fil-A,” Gustin messaged to his more than 172,000 Twitter followers. “Your food is not good enough to take from a bunch of ass holes. @glaad.”

GLAAD responded: “#Glee's Grant Gustin is 'done with Chick-fil-a.' Thanks for speaking out, @grantgust!”

Last week, Boston Mayor Thomas Menino said he would block the restaurant chain from setting up shop in Boston and the Jim Henson Company – the company behind the Muppets – said it was ending its partnership with the company. The actions prompted Fox News' Mike Huckabee to rush to Chick-Fil-A's defense, declaring Wednesday, August 1 “Chick-Fil-A Appreciation Day.”
