I thank the writer for providing me with food for thought, but disagree with his conclusion.

From the article:

"In Boston, Mayor Thomas M. Menino urged Chick-fil-A not to open a restaurant, explaining to The Boston Herald: “You can’t have a business in the city of Boston that discriminates against a population.” In Philadelphia, the City Council member James F. Kenney wrote to Mr. Cathy, instructing him to “take a hike and take your intolerance with you.” A Chicago alderman opposed the opening of a new Chick-fil-A restaurant in his ward. And Speaker Christine Quinn of the New York City Council endorsed a movement by students at New York University who are pushing for the removal of Chick-fil-A from the school’s campus. "

None of the above is Congress enacting any law "abridging free expression..."  None of the above has taken any effective legal steps to prevent the establishment of a CFA.  They have simply exercised their own First Amendment right to free speech, albeit from a more prominent platform than most of us have available.  Officeholders do not forfeit those rights when they take office.  Freedom can be a sloppy, unseemly mess sometimes.  Ah well, there it is, a bunch of mismatched individuals living together with all the burps, farts, warts, and grouchiness that can come with that.  No Chick-fil-A pour moi, an individual, and if my mayor or councilwoman or neighborhood captain wants to speak up for that, so much the better.
