Gay is a Naughty word for the NFL

The NFLShop.com refused to print the name of a player who’s last name just happened to be Gay. A former Professor, of the New England Patriots player Randall Gay, was told that “Gay” is in their list of naughty words. These “Naughty Words” are banned from being printed on the Jerseys of NFL teams. Well I thought gay meant happy and cheerful, how can this be a naughty word? The gay culture has redefined this word, the English dictionary validates this:
gayness n.
Usage Note: The word gay is now standard in its use to refer to homosexuals, in large part because it is the term that most gay people prefer in referring to themselves. Gay is distinguished from homosexual primarily by the emphasis it places on the cultural and social aspects of homosexuality as opposed to sexual practice.

Yes the dictionary lists the definitions of the word gay, and happy and cheerful is second after the definition of a sexual lifestyle. If gay no-longer means happy, then what does it mean to be glum?
