Fired for having a picture of a pint of Guinness?

It seems a Georgia teacher was asked to resign because her Facebook page included pictures in which she was hoisting a Guinness or having a glass of wine or uttering an occasional obscenity. Sounds like crap to me! I say hammer the Barrow County Board of Eduction Superintendent (rsaunders@barrow.k12.ga.us) with e-mails asking why a teacher would be asked to resign for such an innocuous act and/or picture (assuming no other personnel issues)...particularly in the absence of a policy regarding an issue of this nature.
