I was a frequent patron of Chick-Fil-A when I lived in NC but anybody who is honestly surprised by the owner's views must never have actually set foot in one of their establishments. Not only are they not open on Sundays, but they have Bible verses on the walls and stories about the founder's faith printed on the paper place mats. He was never really hiding his views before any of this anyway.
I have never heard of a substantiated claim of discrimination regarding Chick-Fil-A so I really don't care that the owner gives his money to organizations I might not agree with. If politicians in Chicago and Boston are really that steadfast in their opposition to Chick-Fil-A because of their views towards the LGBT community, are these cities also going to stop the Catholic church from opening up new parishes in the city?
