Mayors Michael Bloomberg of New York City and Ed Lee of San Francisco disagree on whether Chick-Fil-A should be banned from cities over its opposition to gay marriage.

After Chick-Fil-A President Dan Cathy conceded that his company is opposed to gay marriage and supports groups opposed to the institution (donating $5 million between 2003 and 2010), Boston Mayor Thomas Menino wrote a scathing letter to Cathy in which he said that his fast-food chain was not welcome in Boston. Chicago Mayor Rahm Emanuel agreed, saying, “Chick-Fil-A's values are not Chicago values.”

But Bloomberg, a strong marriage equality advocate, said he “really strongly” disagrees with banning a business based on the personal beliefs of its CEO.

“You can't have a test for what the owners' personal views are before you decide to give a permit to do something in the city,” Bloomberg told reporters on Friday. “You really don't want to ask [about] political beliefs or religious beliefs before you issue a permit, that's just not government's job.”

Lee on Thursday tweeted, “Very disappointed #ChickFilA doesn't share San Francisco's values & strong commitment to equality for everyone.” He added in a second message: “Closest #ChickFilA to San Francisco is 40 miles away & I strongly recommend that they not try to come any closer.”
