And you thought the matter of replacement referees was controversial.
Earlier this season, Baltimore Ravens linebacker Brendon Ayanbadejo publicly expressed support for same-sex marriage.
In response, Maryland state delegate Emmett C. Burns Jr., a Ravens fan, wrote a letter to the Ravens owner, Steve Bisciotti, asking him to prohibit his players from offering political commentary.
Outraged by the Maryland politician’s letter, Minnesota Vikings punter Chris Kluwe penned a lewd, rude and profanity-laden letter to Mr. Burns, chastising him for not only encouraging censorship but also, supporting traditional one-man, one-woman marriage.
