I mean you take the good with the bad, and it's on a chicken franchise to determine how interesting they think it is to have their progressive Sunday policy framed next to their stance that gay people shouldn't be able to marry.
Has CF ever directly prevented a gay couple from getting married? Has any organization they have donated to ever directly prevented a gay couple from getting married?
Just because an individual or a company is perceived as disagreeing with your personal beliefs doesn't make it 'bad'.
CF happily sells its delicious chicken to everyone irrespective of their sexual orientation.
