In an editorial today, the Philly Inquirer salutes the "holiday" light display at Philadelphia's City Hall. Nowhere in the editorial was the word "Christmas".
I am not accusing the Inquirer of being politically correct; I can only assume the city decided to name the light display "Holiday" display. That's a little surprising for mayor John Street- I am not a fan but I did not think he would succumb to this type of PC overkill.
Here is the link to the editorial for your reading pleasure.
